On top of my issue with the segmentation fault on the writeconf, PHP won't load on websites 50% of the time. Here is an example of what I will see in my web-browser instead of the website...this just started happening after I reinstalled ISPCONFIG trying to resolve the writeconf problem. Basically, all of my PHP sites will only show the website content 50% of the time. The rest of the time, the web-browser shows the source-code. PHP is enabled and SAFEMODE is disabled for all websites.
This has been resolved. I moved the two year old configuration files in /etc/httpd/conf.d/ to be used instead of the recently created files by the last upgrade/repair attempt on ISPCONFIG. It seems to all be working now.
