E-mails look weird

[Norwegian_Rat]

Hi

We have encountered an unusual issue we just cant seem to get our head around.

Following our update to the latest bleeding-edge version, all functionalities within the back office appeared to operate smoothly. However, we have noticed that the emails being sent out are not rendering correctly. This problem did not exist prior to the upgrade; now, emails sent from both /mails and /modules/mailalerts are displaying styling code, with addresses replaced by random characters, and the emails are not presenting well in mail clients on either mobile devices or desktop browsers. Additionally, the logo image appears blurry and has a significantly degraded resolution. I have attempted to replace the folders with the original ones from the download file and have also tried using older versions, but these efforts have not resolved the issue. We also tried a new upload of the mail logo, but to no avail.

We are currently operating on version 1.7.0 with PHP 8.3.

Has anyone else experienced this problem? If so, does anyone have any suggestions for a solution?

We're on bleeding edge and do not have this problem.

It looks like some errors in the code of your own modified email templates in the /themes/_YOUR_THEME_/mails/en/ directory.
You can check this by copying templates with a name starting with order_conf from the /mails/en/ directory to the /themes/_YOUR_THEME_/mails/en/ directory.

Thirtybees update process does not update email templates from the /themes/_YOUR_THEME_/mails/ directory.
