UBB.threads PHP Forum Software Community Forums UBB.threads 7 Bug Reports Fixed Bugs [FIXED for 7.5.1] PM Icon not flashing since 7.5 here on this forum

I updated our board to 7.5.2
The PM indicator is flashing, but there is no mail in my box.

I checked this effect from several PC - the result is same.
I checked from IE and Firefox.
It looks like my profile MySQL data is not changed ...

This effect works only for me and another person (I asked friends about this effect)
