I have a error that I work on for a wile now and I can't figure it out.
I work on a website called: www.palmisuzutruck.com
If I open the site in IE or an Incognito Window in Chrome I get a 500 Error in IE and a blank page in Chrome same in any mobile browser.
However, if I reload all loads fine. I can repeat this and it happens every time.
initially I had the DNS for this domain on my own server but than I moved into GoDaddy DNS and forgot to remove the DNS entries in my BIND server. So I thought there maybe a DNS issue. However I delete the DNS entries on my server on Saturday. Still it is happening.
Since this is a wordpress site I naturally assumes it would be a cache issue. I saw there was SuperCache plugin on there. I deactivated it and removed the plug-in all together, including all cache related items in the config file. Still same issue. Strange is also that it even happens in the WP login page which is not really connected to an theme or plug-ins.
I checked the virtualhost entry in Apache and all looks file like all other domains.
I checked the htaccess file and it seems to be fine too.
So I am not 100% sure what else to check so I thought I would post here and see if anyone maybe had something similar and has some troubleshooting tips. I would be very happy to get some tips or maybe even a solution to this issue.
The system is running on lates wordpress, apache server, linux CentOS 6.7, PHP5.4
if you like to know anything else please ask me.
Thank you for assisting
