Question:
Sometimes my browser tries to download or save php files from my website. What causes this? How can it fix it?
Answer:
This can happen for a variety of reasons. However we frequently see it when a page is timing out. If you are connecting to a remote database make sure that the database is up and that dns is resolving correctly for it.
Found the problem. The following lines were in my original .htaccess file:
# Set the catch-all handler to prevent scripts from being executed.
SetHandler Drupal_Security_Do_Not_Remove_See_SA_2006_006
# Override the handler again if we're run later in the evaluation list.
SetHandler Drupal_Security_Do_Not_Remove_See_SA_2013_003
and WERE working before the update. I commented out those lines and my site is running again. Thanks for providing a place for sharing tips!
