In a new 24.x vcs master installation the tiki-admin_modules.php UI is broken.
The UI is kind of cut-off below the module zone tabs and there is no button to add new modules. The interface seems to have been reorganised, but not finalised yet.
When activating and deactivating (playing around) the tabs / no tabs buttons the button appears.
I will try to confirm with show.tiki.org confirmed
There seems to be a conflict with two variants of the tab toggle (tab view / no tabs) and and a duplication of the admin module tabs. See attached screenshots.
I assume a template issue
The URL for the show2.tiki.org instance that demonstrates this bug is at: http://torsten-11143-7967.show2.tiki.org. Note that if you get a popup asking for a username/password, please just enter "show" and "show". This is different from the initial login and password for a new Tiki which is "admin" and "admin".
For the install log, see http://torsten-11143-7967.show2.tiki.org/info.txt
Note that if you see PHP errors or a Tiki claiming to be missing third party software, the instance creation is probably not finished. Please wait a couple minutes and reload.
Snapshots are database dumps of the configuration that developers can download for debugging. Once you have reproduced your bug on the show2.tiki.org instance, create a snapshot that can then be downloaded by developers for further investigation.
Snapshots can be accessed at: http://torsten-11143-7967.show2.tiki.org/snapshots/. Note that if you get a popup asking for a username/password, please just enter "show" and "show".
Create new snapshotTo help developers solve the bug, we kindly request that you demonstrate your bug on a show.tikiwiki.org instance. To start, simply select a version and click on "Create show.tikiwiki.org instance". Once the instance is ready (in a minute or two), as indicated in the status window below, you can then access that instance, login (the initial admin username/password is "admin") and configure the Tiki to demonstrate your bug. Priority will be given to bugs that have been demonstrated on show.tikiwiki.org.
