Cannot add or edit Joomla contacts from the administration

Question

In the administration side, in my components, and on the contacts page, I cannot edit the contacts (add or save or close). The page is struck - all that I have to do is close the tab.
I tried in changing the permissions level too, but the issue remains the same. Please suggest to me some ideas.

Answer 1

Different solution: simply disable the osolcaptcha plugin while editing contacts. Most likely, contacts will not have to be updated very often.
