Could you tell me which version of that plugin you have? Could you check with a fresh copy with the latest version of Product Bundles if the error persists? Perhaps if you are using Product Bundles version lower than 4.11.4 this might happen. * Thread Starter [rhkavli](https://wordpress.org/support/users/rhkavli/) * (@rhkavli) * [9 years, 1 month ago](https://wordpress.org/support/topic/error-after-plugin-upgrade-from-admin-page/#post-8949838) * Hi George, * I do not have a plugin named Product Bundles, neither active nor passive. * I was asked to enable the PayEx GW for this customer and to update the framework and plugins.

I was just looking for “Product Bundles” without any prefix. Will upgrade, re-enable and get back regarding the result. * Btw: Is there no dependency checking, when doing bulk upgrades? Hereafter I realize one should be bl**dy careful regarding the upgrade sequence. * Thanks again, * — R * [George Botsev](https://wordpress.org/support/users/botzev/) * (@botzev) * [9 years, 1 month ago](https://wordpress.org/support/topic/error-after-plugin-upgrade-from-admin-page/#post-8949906) * Please remember to create a backup copy first – as a good practice when updating. * Thread Starter [rhkavli](https://wordpress.org/support/users/rhkavli/) * (@rhkavli) * [9 years, 1 month ago](https://wordpress.org/support/topic/error-after-plugin-upgrade-from-admin-page/#post-8949940) * I know too well. But there was too little space on the server to make a backup! That is being remedied by the site owner, as well. * It is a snapshot of a sister-site, without any customer data, so that’s why I shot from the hip. I’d never do it in a production environment. * — R * [George Botsev](https://wordpress.org/support/users/botzev/) * (@botzev) * [9 years, 1 month ago](https://wordpress.org/support/topic/error-after-plugin-upgrade-from-admin-page/#post-8951362) * I hope that everything goes fine during the update.
