Hello,
Thanks for your efforts.
We found what was the reason of the issue 🙂
You have an account element in the header with dropdown content and an enabled option of registration in WooCommerce settings. Previously we disabled account off-canvas and dropdown on account login/register pages (to prevent double login/register forms and scripts conflicts). But we didn’t check the page of dokan (that you found now) that makes the same login/register actions. From now we will disable account dropdown/canvas on this specific page as well to allow dokan scripts load in the right order and work as expected.
The fix is uploaded for you in xstore/framework/compatibility/dokan.php (staging01)
Also, it will be included in next theme update !
Please, check if the issue was fixed and give us feedback 🙂
Regards
