I can't seem to add a category to my Hotspots. I was running on 1.5.20, but even after updating to 1.5.25 it's still not working.
I updated the mootools plugin, I even tried the following plugin: http://www.seblod.com/support/documentation/others/mootools-upgrade-plugin.html and changed the settings to have Mootools on 1.2, in the backend and on the site itself.
Even now, I still cannot add a category, cause I can't click 'Save'. When pressing Enter (thus saving it), it gives me the error
'Fatal error: Call to undefined method HotspotsModelcategories::getCategory() in /www/v/a/n/xxx/public_html/administrator/components/com_hotspots/views/editcategory/view.html.php on line 32'
I cannot migrate to 2.5 or anythine, cause my other neccesary compents are not compatible.
