I get the following error on all ads when I try to adjust priorities etc (all of which are currently running). Has there been a change to naming? I don't want to have to rename and re-upload all of my ads.
Invalid filename. The filename "Access Infinity Mobile Leaderboard (300 × 50px).pn" has invalid characters in it. Please rename the file to only use letters, numbers, hyphens, underscores and periods.
This is now fixed. Now the system only validates filenames on new Ads.
We recently put validation on filenames because some users were running into issues with symbols in their filenames breaking their ads in certain browsers/situations. It's best to only use letters, numbers, hyphens, underscores and periods for the filenames of any files that you want to use online.
