Hi there,
Is there a way to keep the EasySocial Search facility but turn off Advanced Search feature?
Currently, there are no setting to disabled advance search on backend. But, maybe you can try to replace attached file on each path below respectively.
.../components/com_easysocial/themes/wireframe/search/default/default.php
.../components/com_easysocial/themes/wireframe/search/mini/default.php
Note:
Attached file name is changed to mini_default.php to differentiate each file because both file is same name. Make sure you rename it to default.php first then replace them at respective path.
Please give it a try and see how it goes.
