Hello everyone,

So I recently started work on a friends silverstripe website, and I didn't know much about it and have been teaching myself how to work and edit the sit over the course of a month. Recently I updated the software to the latest 2.3.4 version hoping it would fix some bugs that had existed in the older one. Instead, it won't allow me to use the gallery and newsletter modules anymore, giving me the attached errors for each. With the gallery module I already spent a few hours trying everything that I could find in the documentation and the forums, and I even reset the db and started with a fresh install of the module, and now everytime I try to select the extension to show images, it will crash, and if I deselect all the extensions, I get a blank template page, but nothing else. yes, I checked the permissions. The newsletter used to work fine, but now I click on it in the admin page and I get the attached error screen.

Any guidance would be appreciated

Thanks

Actually, you don't need to do any of that. All you need to do is upgrade the newsletter module to the latest 2.3 compatible version from SVN (which is probably trunk). The gallery module however has not been maintained for ages and ages and is probably not compatible with 2.3.4. The Image Gallery module is probably the best alternative to use.

Just something you might be interested in (but I'm still using Silverstripe 2.3.3):

For a working Newsletter subscription validation change the lines 140+141 in SubscriptionPage.php (version: newsletter-trunk-r94397) to:

Requirements::javascript("http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js");
Requirements::javascript("http://ajax.microsoft.com/ajax/jquery.validate/1.5.5/jquery.validate.min.js");

For adding users to a list always first define a newsletter type under the tab 'newsletter' and choose a group you defined before under security. Then choose in the page subscription form the right newsletter for 'Select the newsletters that you want the user subscript to'. But I'm still using 2.3.3.
Probably something important changed? http://open.silverstripe.org/wiki/ChangeLog/2.3.4
