Page builder not working anymore

Hi,

I’ve reached a dead end. This morning, my website looked all jumbled up. So I logged into the back end and noticed that no content is displayed on my pages (so I suppose the page builder is the issue). Just to be clear: I did not lose my content altogether, it is still displayed on my website. But it looks like s&*^&. And I cannot edit it in the back end.

I googled and googled and googled. So far I’ve tried:
– check if this was a plugin “disagreement”
– use a different theme by siteorigin
– check for javascript errors
– check the wp-config.php file (debug : false)

My last idea was to rollback to wordpress 4.6 (i was on 4.6.1). That didn’t do it either.

I have now activated the maintenance plugin because the site really does not look good.

I’m not really a techie, and I’m just at a loss here. The only thing that has changed since yesterday was that I had Google fetch and crawl the site (yesterday my site looked fine!).

Please help :(

I’m using the Sydney theme, pagebuilder version 2.4.19.
