&463/ Hands-on: Migrating a Movable Type 3.35 Site to 4.21. Part II.

But unfortunately, for important functions as revising an existing entry or publishing a new one, it still gives me

Server error!
The server encountered an internal error and was unable to complete your request.

Error message:
malformed header from script. Bad header=Out of memory!: cgiwrap
If you think this is a server error, please contact the webmaster.
Error 500

When I won't be able to resolve this, I will have to roll back :(

PS: Yes, I have performed CHMOD 755 for all CGI files and 777 for the support folder ...

To be continued ...
