Can't save on Accordion Menu module/changes aren't saved

For the latest Joomla versions you need to have the latest Accordion Menu versions, because the module saving doesn't work with older versions. So update your Accordion Menu and that will probably solve your problem!

If it wouldn't, there could be another extension running wrong codes on your site, causing javascript errors. Use Chrome or Firefox to identify the cause -> go to our module, where you cannot save -> press F12 -> click on Console -> refresh the page. In the Console an error message should appear pointing to the wrong extension and you could try to turn off that extension or contact their developers.
