I got a reply from Viadat by email with a solution, which i want to share with you if anyone encounters the same problem.
You can go to your ‘sl-functions.php’, in the ‘sl_add_options_page()’ function, change the ‘capability’ element in the arrays used to create the admin pages (approx. starting at line 436).
The downside of this method is needing to modify this after each Store Locator update. Currently, working on developing an addon that allows you to grant specific role access to each page/sub-page of the Store Locator plugin, so hopefully will be available in the future
This solution works fine till they have developed a better way to do this.
Have a nice day!
