I've been working hard on a site that's going to launch soon, but I've been noticing a bunch of 500 internal server errors happening lately (a few a week). I didn't enable debugging mode during development (I know...I should have) -- so I don't know what's making the errors. A simple reset of the htaccess file always brings my site back up quickly, but... I don't want this to keep happening.
I can try and enable debugging in the little time between now and launch, but...is there anything else I could be doing in the meantime, or looking out for, to ensure this doesn't keep happening? I increased memory a while back. After launch, I really need this site to be stable.
Thanks in advance for any suggestions/advice!
