I uploaded a contest entry, then tried to upload something in the Images Showcase gallery and got this, incorrectly:
An Error Has Occurred!
You have exceeded your maximum upload per day. Upload limit per day is 3
It would have been my second (not fourth) upload of the day.
Either somebody else was able to login as me and uploaded two images between midnight last night and now, or something has gone seriously wrong under the hood.
Viewing
http://www.fractalforums.com/index.php?action=gallery;sa=myimages;u=511 establishes that the former did not occur -- there is only one item dated May 17 (as of this writing), rather than the three that would be required for the above error message to not itself have been generated in error. So something's gone wrong with whatever enforces the upload limit and is causing it to trigger after the first upload of the day rather than the third.
Whatever the problem is, it seems to have started today; the same link shows that I was able to upload the nominal maximum of three items yesterday so it cannot have existed yet as of 9 last night when the third of those was uploaded. The problem developed between 9 last night and 3 today, an 18-hour period. Perhaps there's something in the logs in that window that might shed some light.
Needless to say, this must be fixed promptly. It will probably interfere with the contest if allowed to persist. In the worst case, someone assuming the limit is still three might go to make three last minute contest submissions on the final day of the contest not realizing this problem exists and they needed, because of it, to make those submissions on the three successive final days of the submission period. Two of their submissions wouldn't be uploadable until after the submission period ended in that case.
Perhaps the limit should also be per gallery? It was imposed to stop people flooding particular galleries, especially the Images Showcase one, after all. In fact the contest ones might as well be exempt entirely since there's a limit of three per user
period in each of those and any further ones will be disqualified; and, again, whether the bug I've encountered today is fixed or not the upload limit could interfere with people's ability to make last-minute submissions on time.
I'd suggest a limit of three per user per day per non-contest gallery, except the user's own gallery, and three per user per contest gallery, if you want to add technical enforcement of the contest's three-per-section-per-user rule. The latter should be "circumventable" by deleting one or moving one out of that section and uploading another, as well, during the submission period so users would still be able to replace an entry if they so chose, even after uploading three in that section. (And a loophole to watch for would be users uploading to their own gallery and then moving to other galleries; items moved out should count the same as uploads to the other gallery vis-a-vis limits, and a move should fail if that move would exceed the destination's limit.)
