Dear dnn-fellows

I've setup a new site with version 4.0.3 a few weeks ago succesfully.
I've upgrade that site to version 4.3.1 with the upgrade source without errors.
I've upgrade that site to version 4.3.3 with the upgrade source without errors.
I've setting up http blowery compression succesfully with the following settings.
<configuration>
  <configSections>  
    <!-- HttpBloweryCompression BEGIN -->
    <sectionGroup name="blowery.web">
      <section name="httpCompress"  type="blowery.Web.HttpCompress.SectionHandler, blowery.Web.HttpCompress"/>
    </sectionGroup>
    <!-- HttpBloweryCompression EINDE -->
  </configSections>
...
...
  <httpModules>
  <!-- HttpBloweryCompression BEGIN -->
    <add name="CompressionModule" type="blowery.Web.HttpCompress.HttpModule, blowery.web.HttpCompress"/>
    <!-- HttpBloweryCompression EINDE -->
  </httpModules>
...
...
  <!-- HttpBloweryCompression BEGIN -->
  <blowery.web>
    <httpCompress preferredAlgorithm="deflate" compressionLevel="high">
      <excludedMimeTypes>
        <add type="image/png" />
        <add type="image/jpeg" />
        <add type="image/jpg" />
        <add type="image/gif" />
        <add type="application/zip" />
        <add type="application/x-zip-compressed" />
        <add type="application/x-gzip-compressed" />
        <add type="application/x-compressed" />
        <add type="application/octet-stream" />
        <add type="application/pdf" />
      </excludedMimeTypes>
      <excludedPaths>
        <add path="Install/" />
        <add path="Webresource.axd"/>
        <add path="ebresource.axd"/>
      </excludedPaths>
    </httpCompress>
  </blowery.web>
  <!-- HttpBloweryCompression EINDE -->
</configuration>

After that I had no time to check if everything works...
Today I want to begin to put some content and do some settings.
But the first thing that I saw was that the expand-collapse of the help icon don't work (I also do'nt see a tooltip).
I'm wondering if there were other things that shall not work.
Who can give me some ideas to fix it?...
Is it better that I overwrite the whole site with the source of the install version?
