 * Hi,
 * I’m currently using the free version of the plugin and want to upgrade, but need
   to be sure I won’t have this issue:
 * I can only select a maximum combination of 3 filters before I get a 403 error.
 * I have different towns as categories and other features as tags. I would like
   to be able to select multiple options with the checkbox option.
    For example:
   3 towns + 2 tags then it should display options with those choices in it using
   the and operator.
 * Thanks for your help
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffilter-combination-error%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello,
 * Our plugin uses `+` symbol for AND operator, but your site convert it to `%2B`.
   
   But it seems that on your server symbol `%` is denied. Please try to toggle option“
   URL decoding” in plugin settings -> SEO tab.
 * Regards,
    Oleg

 * Ok great, it’s working thanks Oleg.
 * Bought the premium version to be able to go into the SEO.
 * This was selected and wasn’t working correctly still giving 403 error.
    URL decoding–
   > Decode all symbols in URL to prevent errors on server side
 * I deselected it, and now it’s working.
