Worth adding that there have been several problems with the Avada theme in the past and it is worth doing a search here to hunt some of them out.
Some issues were sorted by an update the Avada team put out earlier this year so it might also be worth checking you are using the most up to date version.
Yes I updated the theme recently, that might have caused the issues. I have the latest version of the theme with all the patches and plugins installed and up to date.
What I mean with stopped working is that I click the buttons and absolutely nothing happens, there's no error message or anything. I see the forum just fine but when I push the reply, add topic or upload buttons they do absolutely nothing.
do you have a link to your site so we can check for obvious conflicts?
no caching of forum pages, right? any errors in the browser console or the php error log?
does this theme use bootstrap.js (which conflicts with the wordpress supplied jquery ui)?
The link is http://automotrizenvideo.com/forum
not sure I can see much since forum seems behind paywall... but it is throwing js errors which might indicates a problem and will stop other js from running...
do you know what fusion-scripts is??
its quite odd to be running scripts from that upload directory too... you might check the integrity of this???
