 * Hi all!
 * Does somebody know anything about this? An error message appears in the WordPress
   administration and I can not access the Media Gallery, I can not edit the WooCommerce
   products and it does not allow me to see them, it seems that the error is being
   caused by the PDF Invoice add-on. But everything worked well for a long time 
   until I updated the latest version of the Divi Theme. The Developers of the Theme
   told me that I had to talk to the creators of the plugin.
    Message:
 * PO \ WC \ PDF_Invoices \ Documents \ Pro_Document :: get_settings () should be
   compatible with WPO \ WC \ PDF_Invoices \ Documents \ Order_Document :: get_settings(
   $ latest = false) in /usr/home/vegan-tattoo.com/web/ wp-content / plugins / woocommerce-
   pdf-ips-pro / includes / documents / abstract-wcpdf-pro-document.php on line 
   23
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fstrange-error-30%2F%3Foutput_format%3Dmd&locale=en_US)

 * This error is the result of an old version of the Professional extension being
   used with a newer (incompatible) version of the free base plugin. If you update
   the Professional extension to the latest version (2.2.15) that will remove this
   error. More about updating: [How to get the latest version](https://docs.wpovernight.com/general/how-to-get-the-latest-version/)

 * Thanks for your answer;
 * I acquired the professional version of the plugin, “WooCommerce PDF Invoices &
   Packing Slips Premium”. I just followed your instructions and installed the “
   WP Overnight Sidekick” plugin and added the License Number but it has been thinking
   for a long time and does nothing else. It seems that he has been trapped.
 * This error does not allow me to work correctly. These problems should not occur
   when paying for a Premium License.
 * Anything else I can do to solve the problem?

 * Which version of the Professional extension do you currently use? Are you sure
   your license is still valid? I see a license purchased with an email address 
   starting with ciberdom@ but that expired in January of this year and wasn’t renewed.
 * Please check that your license is still valid, and send us an email at [support@wpovernight.com](https://wordpress.org/support/topic/strange-error-30/support@wpovernight.com?output_format=md)
   and we’ll do our best to help – wordpress.org does not allow us to use these 
   forums for supporting our paid extension and in this particular instance I think
   email is more effective too.
 * Thanks and apologies for the inconvenience!

 * I completely agree.
    I just sent the mail to the address you gave me.
