Hi,
I have the same problem check this link.
https://www.gavick.com/forums/free-joom ... 27304.htmlThis is the problem1. There is no problem to create the Tabs, let's say we create 4 Tabs - Tab1, Tab2, Tab3 and Tab4.
2. I save the module and everything is OK
3. Then I go back and rename the Tab name from "Tab1" to "Tab1Test" and click on the "Save" button in the Tab Window and then click the "Save" button for the Module.
4. Then I go back to check the Tabs (still in the Admin Panel) and they are gone.
5. Then I check the "tabs_data" for the particular module from phpMyAdmin and I discovered that the text "null" is added there and it is not supposed to be there. If I delete the "null" text some of the Tabs are shown again in the Admin Panel but not all of them because the "tabs_data" is already corrupted (got corrupted after I changed the Tab name and clicked on "Save").
As a conclusion, if you change the name of an existing Tab and "Save" the Module, the "tabs_data" gets corrupted. "tabs_data" seems to be generated in "helpers.php" so there is something wrong there.
The bug is obvious and easily reproduceable. Please update me on that. Thanks!
