Hi

This problem occurs because of my WordPress language. My site language is Persian (fa). When I set the site language to English, there is no problem and it opens without error.

All plugins are up to date. The WordPress version of the site is 6.7.1.

What should I do to solve this problem?

Please create a new support topic and describe your issue there so we can check it for you.

Hello @viper_razor

I tried AMP plugin on our test site in Persian language and didn’t face any issues, (screeshot)

The issue you’re experiencing might be related to third-party plugins or themes. Specifically, the LiteSpeed Cache plugin sometimes sends JSON data with comments, which can cause problems.

To resolve this, you can add a small piece of code to your website. You have two options:

1. Add the code to your child theme’s functions.php file. This is generally the recommended approach.
Create a custom plugin and add the code there.

The code itself is very simple:

add_filter( 'litespeed_comment', '__return_false' );

This code snippet will prevent LiteSpeed Cache from adding comments to the JSON data, hopefully resolving the errors you’re encountering.

If the issue persists, please consider using Health check and troubleshooting plugin to debug the conflict
here are steps you can follow to debug.

1. Install and activate the Health Check & Troubleshooting plugin.
2. Navigate to Tools > Site Health > Troubleshooting.
3. Enable trouble shooting mode
4. Visit Appearance-> Themes -> Activate Your theme
5. Visit Plugins-> Installed plugins -> Activate AMP plugin
6. Visit plugin -> installed plugins and activate one of the plugin (only one at a time) which was active on your site
7. Check AMP Page version of your page which caused the issue
8. Do you found that issue?
9. if yes then you found culprit report back to us, or check that plugins settings
10. if not continue from step 6

We hope this helps!

@viper_razor As we didn’t receive a response I’ll mark this as resolved. Feel free to open a new support topic if you require any further assistance.

No, the problem is not solved.

@viper_razor does recommendations from my last message helped?

Unfortunately, it didn’t work.

When I change the language of the site to English, the problem is solved, but when I change it to Persian, I run into the problem again.

@milindmore22 Our web server is not LiteSpeed, so we do not use the LiteSpeed ??plugin, but we use the Rocket WordPress plugin. Thank you for providing the function code for Rocket WordPress.
