No worries, Dekel E. I can help you with that.
Go to this link: https://phabricator.wikimedia.org/project/view/549/. Look next to the Search Box. You should see an icon of a window with an arrow in it. Click that icon. It should take you here: https://phabricator.wikimedia.org/auth/start/?next=%2Fproject%2Fview%2F549%2F. You can login with your MediaWiki credentials via OAuth. Then, re-load this page: https://phabricator.wikimedia.org/project/view/549/. You should see a " + " button next to the search box now. Click that icon to add a new Task (aka bug report).
Title: explain the problem very succinctly
Assigned to: leave blank
CC: AKoval_WMF
Priority: needs triage
Projects: MediaWiki-extensions-EducationProgram
Security: none
Description: explain the problem in detail, especially which Wikimedia project. include links to relevant pages. include screenshots if you can (these help a lot!).
If these steps don't work, I can file the bug report for you. Just need to know which Wikimedia project you had the error on? Was this Hebrew Wikipedia? Thanks, Dekel E.
