Warning message

This means some module's code is bogus, as it's passing an array instead of a string. You could try to debug on your own to find out which module calls any of the transliteration_*() functions by inserting something like var_dump(debug_backtrace()); right before line 32 in transliteration.inc.

Hi
I had the same error and removede the module Insert. It look like it solved my problem.

I got this error after enabling te redirect module. No time to dive into it, but disabling solved the problem for now...

I had the same issue using Drupal 7 with Transliteration 7.x-3.0-alpha1.

It seems to be solved in the 7.x-3.x-dev (http://ftp.drupal.org/files/projects/transliteration-7.x-3.0-alpha1.tar.gz) version.

same

I can confirm updating to the current dev version fixes the problem. I also have Insert installed.

Same issue but the Transliteration 7.x-3.0-alpha1 did not solve this issue, I removed Transliteration 7.x-3.0-alpha1 and seems fine ??

Same problem here, warning messages started to appear after enabling Webform module. I'm using Transliteration 7.x-3.0-alpha1 version.

We had the same probelm, but the error messages occurred only if we added a select-option in the webform.

After updating to newest Webform (7.x-3.13) the errors were gone and everything works fine.

Correction: The errors came back after updating Webform module but haven't shown up now after we updated to latest dev version of Transliteration.

I got this error with I go on node/x/webform-results sometimes... if I refresh 10 times I got the error perhaps 4 times. It's a multilingual website but the webforme node type don't have any translation feature activated.

webform 7.x-3.13
transliteration 7.x-3.0-alpha1

That's a quick patch, which resolves the problem.

The function should certainly not be called at the first place no?

This is clearly fixed in the 7.x-3.x-dev version. We'll probably have a new stable release soon so I'm closing this one.
