Hello,
Thanks for contacting us. The “modules” of our plugin are actually Widgets as you may have noticed already.
In order to override the “Search Form” widget and its template file, you should copy the original file default.php from the path that you also mentioned in your message, and add it to the following directory:
/wp-content/uploads/vikrentcar/overrides/modules/mod_vikrentcar_search/default.php
Of course you should create any missing directories from the above path. If the file “default.php” is available in the above directory, then the framework of VikRentCar will actually render your override file where any modification can be placed.
Instead, the file “error_form.php” is not a layout file that supports overrides. You can just edit the main file, and the back-end page Dashboard will back it up for you in order to not lose any changes by installing future and official updates for our plugin.
We hope this helps!
The VikWP Team
