Job ID: 37588553

Budget: €8 – €30 EUR

I have to solve a 404 error on site builded with GRAV CMS (https://getgrav.org/).

The problem is one node of the cms. If you click on WEBCAM section, all pages gives 404 error.

All pages are present, and .htaccess file is ok.
I'm just main admin of this site, so I don't know what some other admin users may have done.
