Lately, the “Merge requests” page in both VTK and Paraview Gitlab has been showing just an error “An error occurred while loading merge requests” in Firefox on Linux (have not tried Windows). With Chromium it works just fine.

 ![Screenshot from 2026-01-15 10-40-17](https://discourse.vtk.org/uploads/default/original/2X/1/1092dbed438bf46560608ccd37e1aba331f47e63.png)

Is this a known issue? Anyone else seeing this?

Hi @hakostra,

Usually when I have such error refreshing the page is enough. Currently it works on my side in Firefox on Linux.

maybe @ben.boeckel can have some insights ?

Works for me in Firefox too. But I’m “always” logged in. Works in a private window though. If you open the Network tab in the Inspector, does it show anything “weird” for any API calls being performed? I wonder if Anubis is intercepting API calls here.

Ok, Ben gave me a hint that lead to a solution. I realized that it worked in a private window in Forefox, so I cleared cookies and site data and then it worked again. Solved. Thanks.
