Bug: Does not work with the 2017 wikitext editor[edit]

@Magnus Manske: HotCat does not work with the mw:2017 wikitext editor. When pressing the save button, it opens the editor without showing the added categories. Daylen (talk) 18:29, 19 May 2017 (UTC)

Bug: recently often fails to load[edit]

For the past month or so, most of the time I open a new Wikipedia page in Chrome, this tool fails to load. Sometimes it sill does (20% time)? I can't detect a pattern. Refreshing the same page several times may trigger the tool loading at some point. Tested on two computers. --Piotr Konieczny aka Prokonsul Piotrus| reply here 06:03, 20 June 2017 (UTC)

It's likely because your user scripts in vector.js or monobook.js are causing errors, which will cause other stuff to fail as well. Wikipedia:Village_pump_(technical)/Archive_155#script_hickups.3FTheDJ (talkcontribs) 09:59, 20 June 2017 (UTC)
I've made these changes: monobook.js and vector.js. It's probably going to be better that way. —TheDJ (talkcontribs) 10:10, 20 June 2017 (UTC)

Adding a category to multiple pages[edit]

Is it possible to use HotCat to add a category to a all the pages in a list? For example I got these files:

And I want to add the category commons:Category:Wrist clasps in the Portable Antiquities Scheme to all of them. Is it possible to do that with HotCat (without manually adding it to each item, of course) or I have to use AWB with a robot account? Fructibus (talk) 18:27, 5 October 2017 (UTC)


Is it possible to have HotCat warn when the category being added is a parent category of a category already assigned to the article? For example, the article is already part of Category:Japanese people stubs and the user wishes to add Category:Japanese people. Will HotCat suggest "Japanese people" in that context? --Big_iron (talk) 19:41, 11 December 2017 (UTC)

While it's usually wrong to add a parent category, in this example it's right, as the article will be removed from the stub category when it ceases to be a stub. PamD 23:15, 11 December 2017 (UTC)
Well I also saw someone use HotCat to add category Category:Canadian people when the person was already part of Category:People from Ottawa which is a sub-sub-sub-sub-Category of Canadian people. --Big_iron (talk) 19:07, 12 December 2017 (UTC)

Firefox 57[edit]

Well, the bad news is this is one of the tools that seems to not be working on Firefox 57 for Linux Mint. Seraphim System (talk) 18:12, 16 December 2017 (UTC)
