I have a multilinguage site using multisite addon to make for each language a diffrent site;
I sell rugs and I would like to install dynamic filter addon for having diffrent search results (by size, style, origin ...)
I installed this addon, but for diffrent attributes that show all languages traduction of attributes at all websites (languages)
for example, for the option size when I turn it to on, I will see at search pages, "size, mesure(french), tamaņo(spanish), dimensioni(italian);
So at the sidebox I will have a list of search fields repeating the attributes in all languages;

Also I have the error

Warning: strlen() expects parameter 1 to be string, array given in /home/o112445/public_html/includes/functions/functions_general.php on line 153


and in top of header:

Warning: trim() expects parameter 1 to be string, array given in /home/o112445/public_html/includes/functions/functions_general.php on line 63


please can somebody help me to make this addon working with my multisite multilingue websites;
