I have a problem in adding new settings to the option tree. I added settings 1 month ago and all was ok. Now I need to add some new settings, but when I click "save changes" it happens a strange things: the new setting is not added to the option tree and lots of previous settings desappear!! But it seems that the the settings are kind of hidden but working, because the site works normally like before.
I really don't know why and I need some help!
i can give the website and / or a dumpf of the database. Please I need very urgent help!!
