Hi guys,
               I removed the following string from the white space filter (under host settings / compression settings)

(?<=[^])\t{2,}|(?<=[>])\s{2,}(?=[<])|(?<=[>])\s{2,11}(?=[<])|(?=[\n])\s{2,}

I now get an error could anyone plese point me to the field in the database where the white space filter data is stored so that i can once again use DNN?

I am currently using DNN Community Version 5.06.01

Server Error in '/dnndev' Application.

Thanks william, I actually managed to figure it out by myself. It turned out there were inconsistencies between the Compression.config in the root directory and the Compression.config in the Config directory.

Root\Compression.config -

<?xml version="1.0" encoding="utf-8"?>
<compression>
  <excludedPaths />
</compression>


Root\Config\Compression.config -

<?xml version="1.0" encoding="utf-8" ?>
<compression>
 <excludedPaths>
 </excludedPaths>

  <![CDATA[(?<=[^])\t{2,}|(?<=[>])\s{2,}(?=[<])|(?<=[>])\s{2,11}(?=[<])|(?=[\n])\s{2,}]]>
 </whitespace>
</compression>


By replacing the file in the root directory with the one in the config directory I resolved my issue.

Thanks for the quick reply
