Tabs don't work

I’m not familiar with the plugin but my first guess would be that there’s a javascript error. Can you check the browser console for javascript errors?

I opened the website, went to Tools=> WP-DB Backup. Then, clicked on a tab. Went to Chrome, clicked on More Tools=> Javascript console. This is what the console said.

6tools.php?page=wp-database-backup:1 Consider using ‘dppx’ units, as in CSS ‘dpi’ means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual ‘dpi’ of a screen. In media query expression: print, not all, (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi)

I pulled up the database in Firefox and the tabs didn’t work. I went to Developer=> Browser console=> JS and it said this:

Password fields present on an insecure (https://) page. This is a security risk that allows user login credentials to be stolen.[Learn More]

These don’t look like errors to me (for the backup anyway).

What else should I do?

Thank you
