I’ve the very same problem, thought something went wrong with one of the upgrades, but even after a new clean install of 1.1.6, I’ve the same strange behaviour. I upgraded php, apache and also mysql to the latest versions (php 5.2.6, apache 2.2.9 and mysql 5.1.29), but still the same!
Maybe it’s a problem with mysql 5.1? I mean, there’re quite a few people out there with this problem, but not enough for a general problem. Which mysql versions do you guys use?
UPDATE: I just tested locally, where I’m running mySQL 5.0.x, and (at least I thought so) Magento 1.1.6 (Upgraded from time to time, started with 1.x something).
There the category admin shows me only “Add New” instead of “Add Root Category” and “Add Subcategory”. I also still can chose the parent category by the dropdown… Okay, this is really strange!
So I checked out the demo store at http://demo-admin.magentocommerce.com/index.php/admin/catalog_category/, to figure out, that I at least couldn’t trigger a freeze while loading.
But I just don’t get a clue of what changed with one of the 1.1.x? Before it was clear how this system works, but now, it seems really messed up.
If I add something to “All Store Views”, it doesn’t show up in the other store views. So do I have to add every category for every single Store View again?! And drag and drop also doesn’t seem to work now. (UPDATE: The drag and drop was an issue because of a not finally loaded page, seems the JScripts sometimes hang a little while loading)
I’m rather confused now and I really hope someone can enlighten me a little…
