"got error useridmismatch" Pop Up after entering a Site

[Maxii]

Hi Guys,

i have a little problem. Every time i edit a site in cmsms 2.1.6 i get a Pop up (screenshot). After double clicking OK it closes. I even have to click on the Pop Up if i want to do something on other programs than my browser. But after double clicking OK i can normaly save and edit it, everything works fine.

I would'nt care about it, because everything works fine, exepct of clicking this away. But it is very confusing for my customer.

Best regards,
Max

Does it do it in a completely clean browser (clear entire cache, history, etc)? Try a different browser, too - ideally with no plugins.
If so, does it do it on all user accounts? Try creating a new account to test (on a clean browser).
Does it do it on a clean install, or just this site in particular?

Hi Digi,

i have tried it in a cleaned brwoser and with a completly new user. I always get the error message.
Also with no active plugins and with all users.

Could it be a server problem? Because the website isn't on our server. Obn the extern server is a strange folder claeed "protect" with an empty php in it, wich we can't delete!
