[WB 2024] Pipe error in testmode Hi, I have a problem when testing a dynamic site. When I test a single page it comes up normally in the browser, but if from that page another page is called or a PageDisplayDialog then the webdev engine has a fatal error. The page shows up briefly, but then this error: The WEBDEV application server encountered an abnormal internal status. Internal code of error: CSCA256 D:\source\source.GP\225129\Release_moteurwebdev_202\srcAwp\CommunicationSessionClientAwp.cpp (255) (21, ERR_INTERNAL) An internal error has occurred. Possible causes: - General protection fault. - Web server, application server, or application configuration error. - Rights error (e.g. the user running the application is the wrong one or does not have sufficient rights). - Error encountered when loading the application. - In IIS, the guest user specified in for the website "Authentication" is different from the user specified in "Handler mappings". De pipe is beëindigd. (109) If I run the project there's no problem, except that I have to login and pick a menu option to run the page. This is a real nuisance I reported this to PCSoft Tech Support, but they said it was due to a change in Chrome and it will be fixed in future versions (of course:X) As I don't intend to enter into the SAAS thing, I wonder if anyone had the same issue and found a worakaound or a hack?

I have a problem when testing a dynamic site.

(21, ERR_INTERNAL)

An internal error has occurred.

Possible causes:
- General protection fault.
- Web server, application server, or application configuration error.
- Rights error (e.g. the user running the application is the wrong one or does not have sufficient rights).
- Error encountered when loading the application.
- In IIS, the guest user specified in for the website "Authentication" is different from the user specified in "Handler mappings".
