Looks like there was an update to your Accordion plugin and now all the accordion data is gone.
Where is the data stored so that I can see if i can find any backups? we had a lot of content and it now says content is missing.
We did not do anything on the website other than edit a Page to add COVID-19 message.
Welcome to our forum.
Not sure which version of accordion you were using, latest version of free should work fine without any problem. although your accordion data still on database, please go to export menu and export accordions post types.
And send me the exported XML file, i will check and tell you next steps.
