According to what I have googled about the error message in the title of your posting this error can occur when trying to use the '.=' concatenation if the left hand side is an array entry but even then it does not occur often or regularly. Which of course does not help much right now...
So here just few questions:
- Disable wildcardurl translation (you can do that in the site.ini under urlsettings) and empty the cache. Does the same error still occur after that?
- Make a lokal copy of the site (maybe without the contents of var/storage if that is to much to download) and try whether the same error still occurs.
- Copy the wild card file from the cache into another , non Z-folder and try to call up the function in there. If that is possible at all - does it work or do you get some error again? - What version of PHP do you use and did you maybe change your PHP version recently?
Hi Claudia, and thanks for your help! Disabling the wildcard translation made the problem go away.
So I guess the issue now is to fix the Wildcard translation..?
My guess is that something have gone wrong when something has been entered into the database. This is a community site, with between 600 and 2000 new objects every day. On another site I'm running the whole site crashed in a similar incident (http://ez.no/community/forum/setup_design/module_ee_not_found).
And I'm also wondering what I've just turned off, when I disabled the wildcard translation..? What on my site won't work?
As far as I have tried it out it is really only the wildcard url translation which is affected by this settings which means you can see what urls will not work anymore in the url translator view.
As for how to solve this problem - I frankly do not know. I would take a look at the ezurlalias table and check whether there are any unusual entries in there. Maybe copy the database to a lokal install and play around with the files involved in url wildcard translation. Check how and where the wildcard cache file is read again - maybe there is an error there. Check for uninitialised variabloes or the string concat I mentioned in my previous post. Unfortunately the error is to obscure (for me) to know exactly what to look for.
Greetings from Luxembourg and good luck
