I have version 0.5.4 of nodebb.
Recently, I also installed a few themes. Can this be an incompatibility issue? Any way to fix this?

Thanks in advance!

I am answering to my question. It looks like the issue came from a theme I installed previously. It works fine after I do the following:

npm uninstall nodebb-theme-cerulean
