Experiencing some turbulence

I knew for some time that a server upgrade at my hosting provider was coming - they were essentially upgrading the underlaying software. (New versions of apache/php/etc. the entire system.) The original time was postponed and I breathed a little sigh of relief because I host somewhere in the order of 7 domains here. Well, this morning it happened and things mostly worked, some of the lesser importance domains were affected although. It took some .htaccess editing and php.ini editing to get everything working. (somehow php.ini had a bit of text that had "word wrapped" and was causing problems.) Also, .htaccess rules were causing the server to offer .html files for download instead of displaying them. All seems to be in order now. Back to regular schedule.
