Forgive me, but I don't know how to troubleshoot this issue.
I built a CMS using PHP/mySQL/jQuery. I designed and tested it on my local machine for a year. I've tested it a ridiculous amount of times, and I never had this happen...
I moved the site to my live server.
The site requires a user login. It's a very big program and has many dependencies that load (jQuery plugins for instance).
Sometimes on a mobile device (iPad, my phone) I get a 500 Server Error and the index/login page does not load at all. I must clear the cache in my Chrome browser to get it to load.
The site will work fine on my mobile device and then sometimes I get the 500 error again! So I have to clear the cache again.
I was getting this issue on occasion with my laptop using Chrome, but that seems to have gone away: I don't get that error. Seems like it's mostly on the mobile devices. Another user though has to clear his cache on his desktop though randomly.
How do I go about troubleshooting this? I really appreciate some feedback. I know I can resolve this.
I figured this out with your suggestions.
I checked the server's error log, and it seems that I had an error with a cookie that wasn't being stored properly!
So, both of you were correct.
Thanks for taking the time.
