marcelstoer on "[Plugin: W3 Total Cache] W3 total cache error: incorrect # BEGIN W3TC Page Cache message"

I just got an email from this forum with a comment that is not listed here. Odd...here it is:

Please check which files are supposed to be edited. The core rules goes into wp-content/cache/page_cache/.htaccess the other rules goes into the XXXXXX/.htaccess file.

I don't have a wp-content/cache/page_cache/.htaccess file. I don't even have a page_cache folder but I have a wp-content/cache/page folder. Should I create a .htaccess file in that folder manually?

If I disable the page cache the plugin tells me

Edit file XXX/public_html/.htaccess and remove all lines between and including # BEGIN W3TC Page Cache core and # END W3TC Page Cache core markers.

which is quite different from the statement above. Totally puzzled now...
