Error : Unexpected token ‘<', " Snippets code

Hello,

I have been experiencing a very frustrating issue with WP Extended for several months.

I can still create new snippets without any problem. However, once a snippet has been created, I am unable to:

• Enable the snippet
• Update the snippet
• Delete the snippet

Every time I attempt one of these actions, I receive the following error:

Unexpected token ‘<‘

What makes this issue particularly strange is that snippet creation works perfectly, but any attempt to modify, enable, or delete an existing snippet consistently fails.

As a workaround, I have to connect via FTP and manually delete the files from the wpextended-snippets directory before recreating the snippets through the interface. As you can imagine, this makes maintenance extremely time-consuming and cumbersome, especially for simple code changes, considering that I currently have around ten active snippets.

I have already performed numerous tests to try to identify the cause of the issue:

• Checked whether the REST API was being blocked.
• Completely disabled Wordfence.
• Disabled all caching on the website.
• Disabled several other plugins that could potentially cause conflicts.
• Performed various compatibility and cookie-related troubleshooting tests.

Despite all these efforts, the “Unexpected token ‘<‘” error continues to occur.

I may have overlooked something. Do you have any suggestions regarding the possible cause of this issue, or could you recommend a more advanced troubleshooting procedure?

If necessary, I can provide:

• Browser console logs
• Network tab errors/responses
• Information about my WordPress environment
• The current version of WP Extended that I am using

Thank you in advance for your assistance.
