Thread:Project:Support desk/Upgrading error ERR CONTENT DECODING FAILED

Hello

I am currently in the process to upgrade my wiki to version 1.20.3 and when I try to run the update in browser mode I get the following error message just before executing the Database update: Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown Error

My current version is 1.20.3 and the URL is http://wiki.medieval-arme.com.ar/.
