Thanks Nayas. none of the above worked.

On other databases I have no issues.

How can i take a backup of the website? It is a simple website and i can repeat it, however, i would like to know what happened and if it is something i did.

Thanks again.

You have to check with the custom modules you have used in the database. As you dont have issue in the other database, just install the custom module you have used in this database one by one in another db and see when the edit option get hidden. You can do this, or you can check the browser console and see whether you get some hint from it

Thanks Niyas

i will try to traceback the modules i installed....

The browser console is showing errors but it is beyond my knowledge of programming.

Example and the list goes on...

web.assets_common.js:3556
