Too high fields for thumbnails and ""An error occurred while processing your request" after upgrade.

[deeuss]

Hi,

after updating the presta to 1.7.6.1, the fields for item thumbnails are too high (website: https://www.secretum-antrum.com/en)

The second problem is the message "An error occurred while processing your request" when choosing the size of the ring and others(https://www.secretum-antrum.com/en/atlantis-jewelry/36-40-atlantis-ring-silver.html#/26 -size-14)

There is a third problem when trying to buy more items (e.g. here: https://www.secretum-antrum.com/en/singing-bowl/440-purple-singing-bowla-crown-chakra-8719497615148.html) the page switches always on the last article from "similar articles" under the subject.

So many problems with a upgrade? Someone can help?
