PHP Warning: strpos() Empty delimiter (while running site on subdomain)

[digitalbricks]

Hello Ralf,

i currently have a website in development running on a subdomain. I use imageTweak and the [[it_gallery]] droplet for resizing images but if i load a page that contains images in the frontent, i get the following PHP warning:

Warning: strpos() [function.strpos]: Empty delimiter in /homepages/(...)/htdocs/web2013/modules/image_tweak/class.filter.php on line 353

(Note: This warning is displayed even the error_reporting() is set to E_NONE in WebsiteBaker settings)

Having this warning, no image is being processed by imageTweak.

After a look at the mentioned file i had the idea that i have to put the subdomain-URL in the imageTweak settings: Admin-Tools --> imageTweak --> Einstellungen --> Domains umschreiben. Having done this setting the warning disappears and the images are scaled and cached correctly. I don't know if the problem is the subdomain or something in imageTweak or the module dependencies. Now it works fine and everything is great. I just want to file this issue for you and others having the same problem.

Best regards
André
