Hey all!

My site is running sluggishly. I'm on VB4.2.5 and PHP 5.6.37.

Server says:

[12-Aug-2018 13:11:22 UTC] PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 1032847313 bytes) in /home/xxxxx/public_html/forum/includes/functions_threadedmode.php on line 23

Server loads are also higher than I'd like and I get frequent 503 errors. In addition, sometimes when I'm on a page typing a post, the page will disappear with a memory error and I lose everything.

What can I do in my settings to fix this?
