There are issues with images displaying and the downloading of files when using compression under DNN 4.4.0. To fix the problem do the following:

Go to Host->Host Settings and uncheck the "Use WhiteSpace filter" checkbox in the Performance Settings section. Click on Update and then Restart Application.

If that doesn't fix the problem then go back to Host Settings and set Compression Setting to No Compression under Performance Settings. Click on Update and then Restart Application.

Alternatively you can try the following that's working for G-Hunter.

Just thought i would comment here that you can use both Compression and Whitespace Filtering in DNN 4.4.0.

Change the default Whitespace Filter to a less aggressive expression listed below:

(?<=[>])\s{2,}(?=[<])|(?<=[>])\s{2,}(?= )|(?<= )\s{2,}(?=[<])

And for the Compression, you may need some addiotional entrys to the Exluded Mime Types list. Here is what i have been using below:

image/gif
image/jpeg
image/jpg
image/png
image/bmp
application/zip
application/x-zip-compressed
application/x-gzip-compressed
application/x-compressed
application/octet-stream
application/pdf

I upgraded my DNN 3.3.2 site to 4.4.0 and have been running the Repository Module just fine with those changes.

I have a similar problem. I wanted to change the whitespace filter settings to (?<=[>])\s{2,}(?=[<])|(?<=[>])\s{2,}(?= )|(?<= )\s{2,}(?=[<]). Unfortunately, I was distracted and pressed update before I applied a new filter. This rendered my production portal non-functional.

How do I reset the default whitespace filter in the database directly? Please advise.

Standing by...

Alex K.

The whitespace filter is not stored in the database, it's in the compression.config file. You'll find it in the root of your dotnetnuke web site. Simply edit the file with notepad. To restore the settings to the default value, paste the following and save the file.

<?xml version="1.0" encoding="utf-8" ?>
<compression>
 <excludedPaths>
 </excludedPaths>
 <whitespace>
  <![CDATA[(?<=[^])\t{2,}|(?<=[>])\s{2,}(?=[<])|(?<=[>])\s{2,11}(?=[<])|(?=[\n])\s{2,}]]>
 </whitespace>
</compression>
