Hi Coracle,
Thank you for writing in, just to clarify the Theme Options are now under X > Theme Options
Now on your customizer issue, please do the following:
- Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
- Reset your .htaccess file by renaming it to .htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.
- Contact your hosting provider to increase your allocated memory limit or do it yourself by adding this code in your wp-config.php file.
define( 'WP_MEMORY_LIMIT', '512M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
You can add it before the line:
/* That’s all, stop editing! Happy blogging. */
Increasing PHP Memory Limit
If the issue persists, please provide us the site URL and credentials in a Secure Note so we can take a closer look.
Let us know how it goes,
Cheers!
