I had been working on a test/staging site for mysite.com and made my site live on Saturday. Since then, I have been getting the following errors 500-error.php?warning.500_internal_error.1. The site appears to be coming up on my end, however still getting errors on Sucuri, GTmetrix, http://mysite.com. Sucuri scanned it for malware and said it was clean. Also, when I tried to check it on wpmudev's uptime - it said "Your domain does not appear to be publicly accessible on the internet. We can only monitor the uptime of public web sites" I also got a 500 error on wpmudev's wp check up. I have turned off many unneeded plugins. Thanks, I would appreciate any help you can provide to help me fix my site.
