Hi All,

I have recently upgraded my server and operating system, and have had my site up and running for a good week, however something really weird just happened. I was wanting to make a few layout changes, so I went into the system admin -> preferences -> general settings and set the "Update module template .html files from themes/your theme/templates directory?" radio button to on.

After the database had updated I went back to my homepage and what I got instead of my site was a blank page with an error message on it saying there had been an internal error. So I pushed the back button and to my relief it appeared the sys admin section was still accessable. I tried reversing the changes I'd made, but to no effect. However, if I set the site to use another theme there was no problem.

My next thought was cache, so I manually deleted the contents of the template_c and cache directories which also had no effect. I turned PHP debug on and when using my theme the debug was showing a whole lot of errors regarding not being able to open cache files. I verified that the files where there and had the correct permissions applied. From here I stopped my site, deleted all the files and restored the entire site (apart from the database) from a known working backup, but still no joy. This meant it had to be the database.

Luckily I had only added minimal data since the last backup, so I deleted the whole site, MySQL database and all and restored from backup again from scratch. It now works, and I was just wondering if anyone else had ever experienced anything like this before, or if you could offer some explination as to perhaps why it happened?
