Edit Toolbar and Twinkle Gadgets are not loading properly at Bengali (bn) Wikipedia
Closed, InvalidPublic


The "Edit Toolbar" and "Twinkle" Gadgets are not loading properly in Bengali Wikipedia. For more that one month we are facing this issue.

The problem is these gadgets do not load all the time. When we open any page in edit mode sometimes these gadgets are missing. If we refresh the pages a number of times the one of the gadgets might load. but i for last one week i could use the Twinkle only a few times.

We discussed this issue at our local village pump and many of the users agreed on this issue. But only one user said that he never faced this issue for the Edit toolbar, but for Twinkle the situation is same for him too.
One of the user reported this issue on the Twinkle project page, but solution did not came[2].

Hi Nasir,
thanks for reporting this.

Looking at the Javascript console in Firefox when loading I get:

Error: TypeError: mw.usability is undefined
Source File:
Line: 8

Error: TypeError: EditTools.createEditTools is not a function
Source File:
Line: 88

For the latter, if you check you can see that the definition for the function createEditTools() was removed already in 2012, but RefToolbarLegacy.js was not updated accordingly.

So that's probably what you want to repair first, and then recheck the situation. and might also be a places for further support.

I'm closing this bug report as INVALID for the time being, as this problem is not about server configuration or MediaWiki code but about local scripts on a specific Wikipedia that anybody could fix on-wiki.
