after updating to v 1.6.2 of zenphoto, zpbase v1.3 is not working anymore - only an empty page is shown. in the error log i get the following:

WARNING: require_once(/path/to/zenphoto/html/zp-core/zp-extensions/mobileTheme/Mobile_Detect.php): Failed to open stream: No such file or directory in /var/www/virtual/hosted/html/themes/zpbase-1.3/functions.php on line 18

problem is, there is no Mobile_Detect.php there, only composer.json composer.lock vendor.

how can i fix this?

The theme has already been updated to this. Use the latest from https://github.com/zenphoto/zpbase

There is no new release version created yet so you have to use the main/master zip via the green "code" button.

Btw, the issue is caused by an update of the 3rd libary in the mobileTheme plugin which changed structure.

thanks for the fast reply!

Many thanks - I've just had the same issue with ZpBootstrap... Now sorted.
