    This shows up when I try to add a new license:

    The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.

    I’m running the latest version of everything.

    Hello @cachhodp,

    thanks for your message and for using my plugin.

    Could you please tell me what exactly the email itself says?

    there is no email. checked spam and everything.

    that itself could be another issue. Are you sure that your WordPress Site is able to send out emails?

    But that’s not the actual problem. Could you send me the PHP error logs? Perhaps there is some relevant entry in there.

    Also, API requests (GET,PUT,POST) return this:

        "code": "lmfwc_rest_data_error",
        "message": "No License Keys available",
        "data": {
            "status": 404

    Error log is empty, I had an expert check it. I’ll send it to you.

    Website is definitely able to send emails.

    error log

    nothing interesting there sadly.

    Do you maybe have a development/staging environment where I could take a look?

    Plugin Author Drazen Bebic


    The problem was the way the product dropdown on the “Add” and “Edit” license page is coded. The plugin retrieves ALL products and puts them in the dropdown. If you have a large number of WooCommerce Products this can make your server run out of PHP memory and throw an error.

    This issue will be addressed in the coming 1.3 release. If anyone else has the same problem please contact me per email ( for a workaround until the new version is released.
