[Plugin: ProjectManager] Upgrade to 1.8.1 problem

Using 2.7, I downloaded the zip file, used the Plugins->Add New->Install a plugin in zip format, and successfully installed and activated the plugin.

Then changed version from 1.8.1 to 1.8.0 and did the automatic upgrade, again, successfully.

Might delete the plugin folder, download the zip, do Plugins->Add New->Install a plugin in zip format, to see if you have success.

Thanks for your reply. I am using 2.6.3. The back end upgrade to 1.8.1 had previously said firstly plugin upgrade successful and database upgrade successful.

I have tried deactivating wp-postratings plugin to see if that was the cause of the problem but front end above error message still occurs (core.php line 102 – missing argument 1)

Reactivated wp-postratings.

As my project wasn’t originally assigned to a category, assigned to “Unassigned” to see if that was a possible cause of the conflict.

Still same error. No obvious white space after end close of php which sometimes causes “Cannot modify header information – headers already sent” error.

I’ve gone back to version 1.6.2 until 1.8.1 is confirmed as compatible with earlier versions than wp 2.7

I am getting the same error in WordPress 2.7.1 with ProjectManager 1.9 so this seems to be a problem across version numbers.

Ok, I just got rid of the problem by upgrading to PHP 5.

I work on several different systems. I have upgraded most to PHP 5 but had missed this one.

@rovers try the following. Change in lib/core.php:

function ProjectManager( $project_id )

into

function ProjectManager( $project_id = false )

Maybe that helps.
