Hi

We've been running the plugin without any issues for a 18 months. We updated to the latest Wordpress (5.4.2) today and are experiencing some problems.

I can't save settings. Clicking the Save button doesn't do anything.

Clicking the Column List button doesn't show the columns. Though selecting individual columns via the table lets me view the column settings - but I can't save changes.

There is text (tooltip text I think) displaying out of place (see screenshot )

Tables still work fine on Front End

thanks 

Just an update - the Debug Log shows this:

I'm connecting to a mysql db on another server - the Test Connection says Successful and the tables are displaying data from it

Hi Aleksandar

You were right - It was a plugin conflict - WP Frontend Profile. I removed it and wpdatatables is fine.

Thanks for your help. Your plugin plus the Filters and Master Details Addons are excellent.

thanks
