Hello! I really hope someone can give me some insight on what might be the issue with a site I'm having. The site isn't launched yet so I don't see a need to share the link and I think I can explain enough without having to share the site. If needed, I will give WPMU access privately.
I use Uptime Robot to monitor my sites. This morning, I got WAY too many notifications about this site going down. The main reasons it gives me is: "Connection Timeout" and "HTTP 500 - Internal Server Error". The site would go down an average of 20-30 seconds at a time and then it would just come back up on its own. It seems to have slowed down with this downtime, but the site sometimes lag and acts really slow. Other times, it works perfectly normal. It's very inconsistent.
The site is on my personal VPS and all the other sites on this server work perfectly fine. I seem to only have a problem with this site.
In addition, sometimes in the middle of working on the site, after I save a page, the page ends up going completely blank and in the address bar, the page's link ends with "options.php" at the end even though I never visited the page. Other times it goes blank and just works fine after a few refreshes.
Does anyone have any insight on why this might be happening? I have no idea how to trouble shoot this as I have never experienced this before.
I don't know if it helps, but I'm using this theme: http://themeforest.net/item/marketplace-wordpress-theme-marketify/6570786
I appreciate your time!
