UddeIM autocomplete not working

Hi. We have installed the plugin on our Joomla uddeIM 3x.
We do not autocomplete works in our sender field.
We installed the system under PHP 5.4.12
We use MEIO
Attached is the error in a print screen.


You could help us? Thank you in advance.

"\index.php\ndex.php?..." seems to be an installation problem, maybe a missing .htaccess file or a wrong rewrite rule.

Hi, we are still having the same problem. Autocomplete name feature is not working.
We are getting the attached java error.

We are not using mootools, we use meio. We have already tried to reinstall twice. But still autocomplete is not working.

If you want we can give you access to our site to let you check it.

Please help us asap since we are getting lots of complaining from our customers because of this failure.

Thanks!

I will check the code again, but a server 500 is usually a server or Joomla misconfiguration (index.php/index.php?...).

Thanks for your answer. We activate the friendly urls and rewriting and continues to give the same attachment error.

Hi, we were reviewing the log. This gives us the plugin error when accessing the input:
