It gives an error when I search by a location field through the Veronika theme on the main page. With other links all is normal. This error appeared when I put manual locations (countries, regions, cities).

Version of osclass 3.7.4,.

My site - ivia.tk
It is a link to the problem - http://ivia.tk/search/cookieAction,done/country,ru/region,781870/term,%25252525252525252525252525252525252525D0%252525252525252525252525252525252525259C%25252525252525252525252525252525252525D0%25252525252525252525252525252525252525BE%25252525252525252525252525252525252525D1%2525252525252525252525252525252525252581%25252525252525252525252525252525252525D0%25252525252525252525252525252525252525BA%25252525252525252525252525252525252525D0%25252525252525252525252525252525252525B2%25252525252525252525252525252525252525D0%25252525252525252525252525252525252525B0

It works on other themes (I checked by osclass wizards 2.0.4), but in veronika it does not.

Debuger shows nothing.

It gives an error in search location field when write of locations not in English (Russian). When I inserted Russian location where "Russia" was writed in english but regions and cities in russian language.

When I wrote (in english) "Russia" - all was ok, but when wrote in russian language it gave an error - (ERR_TOO_MANY_REDIRECTS)

try to use original files of theme, usually it helps )

I use original files

according to mobile view on my phone, icons are looking different size then on original theme.
the link in search pan generated wrong in your site -  too many 252525252.....
it must be
http://ivia.tk/search/orderSelect,new/sShowAs,list

try to  copy original theme files one more time  in your folder,something looks wrong..

I made it (put in original files of the theme) but nothing changed. It is not works just with russian words in location search

I have just seen that it gives an error in bender

(Warning: Illegal string offset 'pk_i_id' in /home/u811802566/public_html/oc-content/themes/bender/search-sidebar.php on line 23

Warning: Cannot assign an empty string to a string offset in /home/u811802566/public_html/oc-content/themes/bender/search-sidebar.php on line 23)

and in osclasswizards

@Eugeniu
It looks like osclass problem to encode this string. Note that each theme has different search parameters and it may work when friendly URLs are not enabled - or conversion to friendly search links does not work.
On our demo site special chars are not supported in URL, there is some special configuration to support different kind of special chars.

you can try insert this code in
 /oc-includes/osclass/formatting.php

// Russian translite code if (is_utf8($string)) { $chars = array( "А"=>"a","Б"=>"b","В"=>"v","Г"=>"g", "Д"=>"d","Е"=>"e","Ж"=>"z","З"=>"z","И"=>"i", "Й"=>"j","К"=>"k","Л"=>"l","М"=>"m","Н"=>"n", "О"=>"o","П"=>"p","Р"=>"r","С"=>"s","Т"=>"t", "У"=>"u","Ф"=>"f","Х"=>"h","Ц"=>"c","Ч"=>"ch", "Ш"=>"sh","Щ"=>"w","Ъ"=>"","Ы"=>"i","Ь"=>"", "Э"=>"e","Ю"=>"ju","Я"=>"ja","а"=>"a","б"=>"b", "в"=>"v","г"=>"g","д"=>"d","е"=>"e", "ё"=>"e","ж"=>"z", "з"=>"z","и"=>"i","й"=>"j","к"=>"k","л"=>"l", "м"=>"m","н"=>"n","о"=>"o","п"=>"p","р"=>"r", "с"=>"s","т"=>"t","у"=>"u","ф"=>"f","х"=>"h", "ц"=>"c","ч"=>"ch","ш"=>"sh","щ"=>"w","ъ"=>"y", "ы"=>"i","ь"=>"","э"=>"e","ю"=>"ju","я"=>"ja", " "=> "-", "."=> "", "/"=> "-", "-" => "-"); $string = strtr($string, $chars); } // End Russian translite code

re-save categories after new code will be inserted. this must help when friendly url is ON and with RU language as well

Oh, thank you very much for your answer.

I put the code in this file and nothing changed. Where should I put this code, on what line?

And there are some other different code lines. May be it needed to perform this code similar?

@Eugeniu
It looks like osclass problem to encode this string. Note that each theme has different search parameters and it may work when friendly URLs are not enabled - or conversion to friendly search links does not work.
On our demo site special chars are not supported in URL, there is some special configuration to support different kind of special chars.

And where can I find these configurations?

@Eugeniu
You will not, best way is to consult with your hosting provider.
