Hi
Still waiting for your help,tried reinstalling Woocommerce and Dokan theme No result, Please help.

hi
still waiting for your reply for the above plugins compatibility with Dokan theme.

thanks
roderswiss it was some issue with Code editor,

I don’t want to add tags and category through the plugin I know it’s not
for that purpose also.
My issue is after editing the plugin file for changing the text “type
here” to custom text the issue started. If I try to add any product tags
or category through backend it won’t add. I deactivated all plug-ins and
tried one by one and found the error when the Dokan search is active. Is it
because I edited the file if so what should I do. Reinstall the plugin or
what. How to change the text in correct way.
I edited the plugin file with text editor in Mac and changed it and
refreshed the file. I don’t think I made any thing else.

waiting for any support on this.Should i need to re install it. i don’t want to edit the Text Type here again. can you please check is it because of the edit it has gone wrong.

Please tell me on How to show the custom menu item on the seller side also, say seller need to select the custom menu item also as he selects the product category. i am waiting for your reply.
