I have a problem that I can’t Add Locations. I open the Store locator Locations Page and I cannot click on the Add. Or any of the other sub menu items?? Tried it on Chrome and Firefox with the same results.
You need to check for conflicts with other plugins. For example Smushit is reported as being a culprit, or any other “minify” plugin. https://wordpress.storelocatorplus.com/forums/topic/admin-section-not-allowing-me-to-click-on-anything/
Deactivate other plugins one by one to resolve. Use WP Debug whenever you have issues like this. It will help you narrow down the culprit
