For my extension
com_XX I created a manifest file name
xx.xml and placed it in the root folder of the extension.
Somewhere, I found an extension that used the name
manifest.xml. Thus I renamed mine.
During installation, no errors are reported.
Suddenly, some parts of my extensions didn't work any longer. Sind I expected other parts of code, I didn't accounted it to the name of the manifest file.
Yet, I was wrong. As I renamed it to
xx.xml, suddenly errors disappeared.
So, what exactly is the right name for the main manifest file of an extenson com_XX?
