Server Error in '/' Application.

---

Hello again,

I found what the problem was.

I had already tried modifying the two httpRuntime elements that were on the file to look like this:

<httpRuntime requestValidationMode="2.0" />

What I hadn’t tried is to add extra httpRuntime elements just before other <pages> elements that didn’t have it. It seems to work now.

Cheers,

Victor

Bumping an old thread here...

Ok so no info that worked was found, I solved the vaildate request issue simply by adding

<pages enableEventValidation="false" validateRequest="false" controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"></pages>

to the  <location path="dropit/plugin/extension/ui/edit">

<location path="dropit/plugin/extension/ui/edit">
<system.web>
<pages enableEventValidation="false" validateRequest="false" controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"></pages>
<httpRuntime requestValidationMode="2.0" maxRequestLength="1000000" />
<authorization>
<allow roles=\EPI_Webadmins_test-U" />
<deny users="*" />
</authorization>
</system.web>
</location>

that worked!
