Hi,
It was indeed the php dom extension that was not installed on the server. It works now.
Thank you for your help.
I uninstalled and reinstalled the plugin, and cleaned up the nging.conf file (=.htacces in appache) and the files in wpcontent as indicated in the link. I tried with no other plugin enabled too.
I can access the plugin menu, but only the top bar appears. The message “critical error” is displayed in the “settings” dropdown.
Thanks for your answers, I’ll see about setting up some redirects on the hosting side.
I’m doing a 301 specific URL redirect from a domain name without www to the same one with www, with the source URL options Ignore slashes, Ignore lowercase/uppercase and Ignore parameters enabled.
