I'm hoping someone can help me, my website, http://sanfelipe.com.mx has started running incredibly slowly and half the time the pages don't even load, but just give a 500 error. The site was running normally, with page load speeds around 1-3 seconds 3 days ago. I haven't added any plugins or themes or done any upgrades, or anything other than very routine work (creating posts). I'm not sure what could be causing the problem. So far I have tried:
- Disabling all plugins
- Switching to default theme
- Resetting the htaccess file
- Checking and optimizing databases
- Talking to my host (who is hostgator, by the way)
Nothing has made any difference. Hostgator informs me that it is something to do with WordPress, but tells me it's something different every time, so I don't think they really know. They do tell me that I'm hitting the process limit of 25 processes at once, but I'm not entirely sure what to begin to do to troubleshoot that.
If anyone can help me or suggest anything at all, I would be hugely grateful... I'm feeling like I've exhausted my troubleshooting knowledge, and think that the only solution may be moving the site to a different host, but it would be hugely disappointing to move it and find the issue still present.
