pdb-single-default.php overwritten despite plugin updates disabled.

Hi There.

I have edited the file “pdb-single-default.php” so that headings and field names no longer appear on my page.

Everything was working fine until the page reverted to its original content yesterday. Obviously this messed up my page because the titles and field names reappeared.

The plugin is not setup to automatically update. Is there something else I am missing that can be disabled to ensure this doesn’t happen again?

Thanks
Don
