Yesterday I installed the report server. Everything seemed to be working correctly. Today when I try to view a report I get this error message "Error registering the viewer with the service. An error has occurred. Incorrect value (null) deserialized. Make sure you are using CacheStorage inside single-instance application deployment only."

In the Schedule I want to set the specific name of the attachment instead of the Report's intern name.

I have a report named Report xyz per period with parameters for day-, week and month report.

When I make a schedule I cannot set the name of the attachment when I sent it by mail, it's alway Report xyz per period.

To localize the reports I now set the Localizable parameter to true and Culture an Language options to nl-NL (for the Netherlands).

So for Dutch customers that will be alright, but when I want to send a report to an English customer I must now make a second report with en-EN.
It will be nicer when I can change that in the schedule.

Though I have overridden the mail template for an individual alert, It is picking up the Configuration | Mail Templates | Data Alert External User for an external email address. However, internal email address gets the right one. 

Please help me resolve this. 

A great feature would be to add security over the connection strings that a user can choose from in the server. We have a development and production environment and we want to allow people to write reports but we don't want them hitting production data because they don't always build efficient queries which can take the production database down.

This would help allow access to development and production separately and help keep the DBA from yelling at me :)

No matter what I try, I get this error when previewing a report:

An error has occurred while processing Report 'SomeReport': Unable to establish a connection to the database. Please, verify that your connection string is valid. In case you use a named connection string from the application configuration file, make sure the name is correct and the connection string settings are present in the configuration file of your application. ------------- InnerException ------------- Format of the initialization string does not conform to specification starting at index 0.

However, everything works great while in the designer.

Any info would help.

The ability to pass a connection string, or prepared data source name, by aspnet/mvc/winforms/wpf viewers.

The current version of reporting service seems to have issues with the newer servicestack libraries. The only way I could get the ServiceStack Service implementation to work is to use the following dependencies (attached). What is the official supported version of ServiceStack and when will newer version be supported?

I am using Telerik Reports Server Q1 2016. I have two problems while configuring the Authentication in Reports server. 

1. Save button hides behind the footer. 
Am unable to see the save button for the authentication section. I have set the position in the developer tools and makes it visible. 

2.The external authentication settings cannot be validated.
I am getting this error while saving the authentication settings. 
Please refer the sample values i given in the field.
