Issues are part of our day-to-day lives so how can technology which is man-made save us from it.

As technological advancement takes place, in the same way, new problems or hindrances are rising in the eCommerce domain in different platforms like Magento which demands expertise.

Being a Magento merchant you must be aware of the problems you have faced or heard in your past or currently that are interrupting your growth to increase sales and conversions, or you might be a Magento developer who is searching for the answers to some of your Magento 2 issues, that’s why we have written this blog, in which most of your queries will be answered.

Besides this, you might be aware that Magento releases new versions quarterly or yearly.

Recently, Magento 2.4.6 and 2.4.7 were launched, and some of the developers personally reached out to us as they were facing some challenges.

So, this blog is also for them. Now, let’s dive deep into this.

Magento 2 Issues And How You Can Fix Them

1. Memory Limit

A common problem with Magento installations is insufficient server memory, which can lead to blank pages or server errors rather than slow performance.

To prevent this, check the memory allocation in the php.ini or .htaccess file and ensure it meets Magento’s system requirements.

Allocating less memory than recommended can cause scripts to crash and prevent the site from loading.

To resolve this, increase the memory limit and test the performance of your Magento backend. You may need to modify the php.ini file or adjust the HTTP access file.

If you’re unsure, consulting a Magento expert can help optimize memory usage for better performance.

2. Using Resource Heavy Themes

The theme you choose for your Magento store plays a significant role in its loading speed.

Heavy themes with excessive code can slow down your site and impact overall performance. Switching to a lightweight theme or optimizing your existing one can help improve speed.

Custom-built themes designed for performance can be a great alternative.

For example, the Magento Responsive Administrator Template allows for visual modifications and UI customization.

However, these changes alone won’t automatically boost performance—additional optimizations may be necessary.

When modifying the admin dashboard theme, developers should be cautious when removing components like Knockout.js, as this may cause certain modules to stop functioning.

Developers should implement workarounds to avoid disruptions.

3. Not Upgrading to the Latest Magento 2 and PHP Version

Many Magento stores fail when it comes to offering smooth and uninterrupted functionalities to their store because you can’t stand in the e-commerce world without keeping your Magento store upgraded to the latest version, as upgradation gives your store optimal performance enhances security by patching vulnerabilities, access new features, improve user experience with a modern interface, and ensure compatibility with the latest technologies, plus each release includes bug fixes, performance enhancements, and new features.

Upgrading can resolve existing Magento issues and improve overall site management.

For example, Magento 2.4.6 introduced several improvements, such as:

Faster response times for product queries in categories with enabled permissions
Optimized GraphQL resolver operations
Improved processing of product permissions

Additionally, upgrading to the latest PHP version with OPcache enabled can significantly enhance performance, making bulk cart operations and product management much faster.

Regular updates ensure your Magento store remains efficient, secure, and optimized for speed.

4. Theme Incompatibility During Migration

Another Magento 2 issue is that it has a different architecture and theme structure, meaning themes from other platforms or Magento 1 are not transferable.

This requires finding a new Magento 2-compatible theme or developing a custom solution.

Solutions for Magento 2 Themes

Use a Pre-Built Theme in Magento 2

You can simply opt for the pre-built themes, that are mostly available in ready-made theme platforms like Adobe Commerce Marketplace, ThemeForest, and Template Monster.

These themes are available in both free and paid, plus different theme designs have different costs based upon the aesthetics, niche, and its complexity which will be fully compatible with your store, and provide you with a fully responsive page for all devices.

Develop a Custom Magento 2 Theme

If your store needs a unique design or specialized features, a custom theme is an option.
This requires significant time, resources, and UI/UX expertise. Therefore, it is recommended that you hire a Magento development agency with experience in eCommerce design, and resolving Magento 2 issues.

5. Security Concerns in Magento

XML External Entity (XXE) Vulnerability

XXE vulnerabilities occur when a system improperly processes XML data, allowing hackers to access sensitive files. This can lead to data breaches and system control attacks.

If an XML file references an external entity, the system may unknowingly retrieve critical server files, such as configuration data.

How to Prevent XXE Attacks:

Always update Magento to the latest version to patch security vulnerabilities.
Check for all the incoming data to prevent unauthorized access.
Web application firewalls (WAFs) will be very useful to detect and block suspicious activities.

Resetting File and Folder Permissions in Magento

File and folder permissions are a common problem with Magento for developers when installing or upgrading Magento or third-party extensions.

By default, permissions may reset during installation, potentially increasing security risks for critical data.

Properly configuring these permissions ensures both security and smooth functionality.

Setting File & Folder Permissions

Magento requires that all files have permissions set to 660 (gives owner and the group to read and write but other users have no permissions) and 770 (gives read, write and execute permission to the owner and to his group, but no permissions to anyone else) for all directories.

To set the correct file permissions, use the following command:

find . -type f -exec chmod 644 {} \;

To set the correct folder permissions, use the following command:

find . -type d -exec chmod 755 {} \;

6. Security Risks in Extensions

Magento extensions play a critical role in improving the overall store functionality, but outdated or poorly coded extensions, especially whose files are downloaded from unsecured sources can create security risks.

Hackers may exploit these weaknesses to gain access to your store or steal customer data.

How to Secure Extensions:

Install extensions only from trusted developers who provide regular updates.
Keep all extensions updated to fix potential security flaws.
Regularly review installed extensions for vulnerabilities and remove any that pose a risk.

7. SEO Issues

Indexing Problems

It doesn’t matter how well your site is created; if there are issues related to page indexing, then your efforts are in vain.

As you might already be aware, indexing issues are very common nowadays and can significantly reduce your store’s visibility.

This often happens when search engines are blocked in the robots.txt file or when the sitemap is outdated.

How to Fix Indexing Issues in Magento 2:

Check and update the robots.txt file to ensure search engines can access important pages.
Submit an updated sitemap to Google for better indexing.
Connect Google Search Console with your Magento store to detect and resolve indexing errors quickly.

Meta Tag Issues

Meta tags play a key role in SEO, and issues such as missing, duplicate, or poorly optimized meta tags can harm search rankings.

How to Fix It:

Make sure that all meta tags are different, and written in an articulative way for all the main pages like the home page, about us, category page, and product pages.
Go for long-term and relevant keywords (primary, secondary, and LSI keywords) to improve search engine visibility.
Another important criterion to consider is to conduct regular audits to align meta tags with the latest SEO best practices, and check for any issues like 404 pages, 301, and so on.

Wrapping Up

Every e-commerce platform comes with its own glitches, issues, and problems.

The same is true of Magento 2, but we can’t deny that it is one of the most powerful e-commerce platforms.

It is also periodically upgraded to offer both merchants and customers a better selling and buying experience.

You can resolve most of your issues by following the above suggestion; however, if you have a complex Magento problem, we are always available for you.
