 * Hey tuttle,
 * Thanks for reaching out!
 * I took a look at your site however I didn’t see the error you’ve mentioned. Were
   you able to get the issue resolved?
 * Thanks!

 * Hi,
 * I had `define(‘WP_MEMORY_LIMIT’, ‘512M’);
    define(‘WP_CACHE’, true);` in my wp-
   config.php. I suppress that, and the message desappear…
 * But I wrote that these codes was important…
 * Do you think my problem is resolved ?

 * Hey [@tuttle](https://wordpress.org/support/users/tuttle/),
 * It’s hard to say for sure if your problem is, indeed, resolved, and if you really
   need those items in your site’s _wp-config.php_ file, then you may find it worthwhile
   to keep investigating this issue.
 * The WP_CACHE line seems to be the problematic one, not so much the WP_MEMORY_LIMIT
   one.
 * Out of curiosity, why did you add these lines to your wp-config.php?
 * If they’re not needed, then you can proceed without them, but if they are, then
   I’d recommend adding them back to your file and then running through the troubleshooting
   steps we have outlined here → [https://theeventscalendar.com/knowledgebase/testing-for-conflicts/](https://theeventscalendar.com/knowledgebase/testing-for-conflicts/)
 * Let us know what you find!
