Hello, I'm getting the following error both on my gallery pages and my image pages:
`Warning: Invalid argument supplied for foreach() in /home/content/b/j/a/bjancewicz/html/ZenPhoto/zp-core/template-functions.php on line 177`
I've tried to go through the entire template-functions.php doc to see if any brackets were missing or anything like that, but I don't see anything missing... does anything stick out to anyone else?
Here is line 177: `foreach ($_zp_plugin_scripts as $script) {'

Actually the problem I've encountered looked alike but is probably not the same: I've realized that my host only uses php 4.4.3 ... then I guess it's just a miracle that zenphoto-1.1.5 worked there (since the front page show php 4.10 as a requirement)
So in case anyone has a persistent problem with the foreach() loops begin given invalid arguments in version 1.1.6, it might be good to know that the previous version (1.1.5) may work well anyway.

However for other reasons, I've transfered my site on an other host, where the newest version of zenphot works pretty well (of course
Thanks for your replies !
We can put a test in to prevent the error, but other things will not work right if `glob()` is not functioning.
Maybe you shouldn't lose too much time on this, though, especially if I'm the only one to have the problem, since my host recently messed up my db in a very strange way and I don't know what else they have done (my wordpress installation is also kind of broken and the db does not seem to be the only problem)
Same thing here, on the same host (free.fr) and put define('SAFE_GLOB', true); in function.php work like a charm
Thanks for zenphoto... really (u rock:)
