Hi @anthonyod,
Thanks for reaching out to the Members Support Team. I understand how disruptive a fatal error can be, and I’d like to help get this sorted out.
Could you please share the exact error message you’re seeing? You can usually find it in the email from WordPress after a crash, or in your site’s error log. Having the specific error text will help me check the issue more closely from my end.
Looking forward to your reply so we can resolve this together.
Best regards,
Hello Omar, Many thanks. Here is the error message detail:
Error Details
=============
An error of type E_COMPILE_ERROR was caused in line 476 of the file /var/www/vhosts/doonfest.org/httpdocs/wp-content/plugins/members/members.php. Error message: Cannot redeclare EC547d38a8E53e8A() (previously declared in /var/www/vhosts/doonfest.org/httpdocs/wp-content/plugins/classic-editor/classic-editor.php:1034)
Hi @anthonyod,
May I ask if you’ve any caching plugins or use some custom code? Because this line in the two plugins is empty. So, am I missing something?
Regards,
Hello again, I have nothing specific for the plugins though I do have WP fastest Cache installed and operational. The Members plugin was the last and most recent plugin I have installed as everything else had been functioning well for a few years prior to this.
If theres any other queries the please let me know as I am keen to make use of the Members plugin as its served my purpose well.
Hello again, did you have the chance to look at this further? Was curious when you stated “Because this line in the two plugins is empty.”
If there is anything I can do to assist then please let me know.
Hi @anthonyod,
Thanks for sharing the error details. The function name in your error isn’t part of either plugin’s code — it’s generated by cached/compiled code. This usually points to a caching issue rather than a direct conflict between Members and Classic Editor.
Please try clearing your PHP Opcache (or restarting PHP), flushing any object cache (Redis/Memcached), and temporarily disabling caching/optimization plugins like WP Fastest Cache. After that, re-enable the plugins and check again.
If the error persists after clearing caches, let me know and we can look deeper into your setup.
Best regards,
Hello again and thanks for engaging with this.
“Please try clearing your PHP Opcache (or restarting PHP)” – Not sure I have access to do this? Is this a server side or wordpress operation?
“flushing any object cache (Redis/Memcached)” -Not sure about this? Where would I do that?
“and temporarily disabling caching/optimization plugins like WP Fastest Cache. ” – I had deactivated this plugin to see any difference but guess I would need to purge the above caches before trying it again.
Its only the Members plugin that there appears to be an issue with as the classic-editor loads and functions fine.
Hi @anthonyod,
Thanks for the follow-up. The caching steps I mentioned (PHP Opcache, Redis/Memcached) are server-side, so if you don’t have direct access, the best approach is to contact your hosting support. Please share the error details with them and ask if they can:
- Clear/reset PHP Opcache.
- Confirm if any object cache (Redis/Memcached) is enabled and flush it.
After they do this, try reactivating Members again (with WP Fastest Cache temporarily off) to see if the error clears.
Let me know how it goes — if the problem continues after your host clears the caches, we’ll keep troubleshooting with you.
Best regards,
Hello again,
The hosting company reset the php and flushed the cache.
I have deactivated the caching plugin and tried to reactivate the Members plugin but its the same message:
Plugin could not be activated because it triggered a fatal error.
Any further help would be much appreciated. Thanks.
Hi @anthonyod,
May I ask if there’s any error added to error log? Please check that with your hosting support.
Regards,
