Hello

I run a large Forum using BBPRESS. Recently, users started being directed to an error page after posting a topic. The error page states:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 528384 bytes) in /home/customer/www/###mysite###.com/public_html/wp-includes/class-wpdb.php on line 2885
There has been a critical error on this website.

I have defined my memory to the max possible: define( ‘WP_MEMORY_LIMIT’, ‘768M’ );

But this had no impact.

Also, what is strange is that despite receiving the error the topic is posted (sent to me for moderation). Once I approve the topic is posted correctly.

Any ideas?
