[SM-PLUGINS] Shared Calendar returns blank page

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Greetings to all,

I am resending this with the correct information per Paul's request...

I have installed the following packages...

calendar_sql_backend-1.1-2.0
compatibility-2.0
shared_calendars-2.0.1-1.4.0

I have modified the configs and enabled the plugins as instructed by the
INSTALL files included with these packages.

I have also enabled debug mode on in the calendar config.php file.

When I click on Calendar at the top of the page I get blank. All I see are
the links at the top of the page, but nothing else.

When I go in to the options...calendar administration at the top of the
page I see...

current username is "tearl"; admin username is "tearl"; are they equal? YES
and a section called Calendar setup with 2 buttons, clicking either of
these give me current username is "tearl"; admin username is "tearl"; are
they equal? YES

... but the rest of the page is blank.

Here are the details on the other packages that we are running...

Line 12 says...

Possible path problem?
