Fatal Error after Articles Install when Article published

Modx Revo 2.2.2-pl
Articles 1.6.3 pl

Fatal error: Call to a member function get() on a non-object in myserveraddress/htdocs/VSF_modx/core/cache/includes/elements/modsnippet/7.include.cache.php on line 21

Modx site on 'live' server (for testing purposes and client feedback) was working fine.
Installed Articles fine.
Create Article resource called rather unimaginatively 'blog' fine.
Manage Articles and create first article fine.
Publish article, clear cache and check site in Firefox 14.0.1 and get the fatal error?
Help please ?

Thanks in advance!

I should add that I can preview the article from within manager but I can no longer launch the site !

Physically remove all the folders in the core/cache folder.

Thanks sottwell - will try that now.

All the folders in the core/cache folder removed - but alas the fatal error remains.

So, when I turn off the Snippet call referred to in the Fatal Error said error is no more. So, can anyone give me an idea as to what in Articles (or my Snippet) is causing this error ? Not sure what to do now.

The line of code referred to in the Fatal Error is :



If this is empty I'm returning the pagetitle instead in a the next couple of lines.

Why would this innocuous line cause a conflict with Articles ?

Anyone ?

Thanks hugely in advance for any help you can offer !!!

I wondered if it was a variable conflict and so change the variable name in the line. Error remained. I guess I have to drop Articles and do it the clunky way… Damn !

Try determining which snippet is #7, then remove it completely in Package manager and re-download and install it again. It looks like something got corrupted somewhere.

Thanks again for getting back to me. You really are the best ! I've taken the decision to remove Articles and have made good progress doing it the clunky way. I'll come back to Articles for another project.

Thanks again for your helpful suggestions.
