CMS Made Simple Forums

Since upgrading from v1.11.3, one version at a time through to v1.11.11, I can no longer add new pages. I can still edit existing pages.

When I attempt to add a new page, I get a blank screen (no HTML is loaded at all, including the <title> etc), and the following error is reported in my server log each time:
I've tried the following:

1. Re-uploading all files from the full core download, and the English-only download.
2. Running the installer again.
3. Running the upgrade again.
4. Removing all UDTs from templates and Events.
5. Creating a new page template and setting it as the default.
6. Setting the existing page template as the default, and applying it to all pages.
7. Clearing cache via the CMS, and manually.
8. Using the default admin theme.

Full system info is below.

Any ideas on what could be causing this, or how I can diagnose further?

You're a genius! You've just saved me from completely rebuilding the site (which I'd literally just started doing). Thanks Robert!

Thank you for providing (without having to be asked) the information we needed to be able to investigate, or reproduce the issue.

Too many people don't provide the information, and therefore don't get assistance.
