I manually update our websites by installing new Admintools version over last one which never got me into trouble before. But while doing the same for 5.3.1 over 5.3.0 I get errors mixed with uninstall message (attached screenshot). The new package seems to be installed anyway and the update does not appear anymore but because of the errors I tried to reinstall it a second time.
On two of the three websites I tested, the second installation seemed to fix the problem completely as it did not show any error and everything seems to be working properly but on the third one (unfortunately first I tried and did not take any screenshot) I then had a second error mentioning something like maximum table locks exceeded and I lost all Admintools parameters, as if I was installing for the first time which of course was absolutely not the case.
Not a very bad issue but as I have to run this update on many websites, I would appreciate any idea on how to avoid the problem if possible of course.
Thanks in advance for your help and have a nice day.
