Undefined constant error after update

Same issue too. In almost all the pages.

Hi there,
please updated to latest available release to fix the issue.
Thank you.

Hello,

Even after updating to 2.0.5.1 I can still see the warning, this time on different line and in different php file:

Warning
:  Use of undefined constant YITH_WAPO_SECRET_KEY - assumed 'YITH_WAPO_SECRET_KEY' (this will throw an Error in a future version of PHP) in /www/wp-content/plugins/yith-woocommerce-product-add-ons/includes/classes/class.yith-wapo.php on line 121.

Thank you for your help!

Im having the same issue ever since 2.0.5. , 2.0.5.1 did not fix it either.

It would be great if you could get your plugin to run again.

I left a request on YITH facebook page and it was recommended I submit a ticket or post here.

Please fix this, I love using your products because normally they just work.

@tgchr you can disable the plugin by connecting to your server via FTP/SSH (or File Manager in your hosting CP) to the wp-content/plugins folder and remame yith-woocommerce-product-add-ons to yith-woocommerce-product-add-on or switch your PHP version to 5.4 temporarily, which will allow you to access the admin panel.

@mtecuk Thanks, I just restored a backup from immediately before the 2.05 update, and was able to log-in and disable the plugin that way. Haven’t had time yet to test the latest updates.

Same issue on version 2.0.5.2

Website URL food-delivery.yourmannar.live

@alessio91 I’m still getting the same error messages with 2.0.5.2, though at least I can still log-in to deactivate it without restoring a backup.

Hi there,
we have found the problem, we will release a new update in the day.
