I have a wordpress plugin that has a few minor problems due to some changes in wordpress 2.7 and php 5.2. These are all minor changes as I had tested it with 2.7 beta to ensure compatibility with most features.

I will supply someone to work along side you who will be there to answer any questions they can as well as showing you the locations of each error on the user side.

Benefits
I will offer benefits if I am happy with your overall work. I will also put you first in line for all other changes that are planned for the future. The bonus you receive will vary depending on the work you provide and could be as high as the cost of the work. ie, double payment.

The problems/required changes are:

1) Problem for users when logging out using wpm widget in sidebar.
Wordpress have changed the link that is used when logging out of
wordpress. This happened in their 2.7 release. The plugin has a widget
that site owners can use, but the logoff link currently produces an
error.

2) One off payments are not working. The plugin offers Subscriptions
or one off payments. When the one off payment option is used, the
users are not activated after paying. The plugin uses IPN. I assume
there is an error in the coding that is stopping this from happening by
not including the information that is required for IPN to operate correctly.

3) When a user views their profile within wordpress, they see an upgrade/downgrade link. This should show them available subscriptions so that they can change their account subscription if they want to. Currently, this does not work and produces an error. It is likely that it is simply an
error in the code used.

(Problem #4 is not something you will be required to work on as part of this job. Instead I would like you to suggest something that can be done. This would then be listed as another job for you unless you think it would be a quick job.)

4) Clean pages. I would like you to suggest a way that we can tidy up
the registration pages and upgrade/downgrade page. I currently use BM
Custom Logon that uses a background image. This works for the
registration pages, but leaves 2 other pages without a style
(subscription page, upgrade/downgrade page). There is already code
within my plugin that provided a background image styling for the
internal pages, but since the wordpress 2.5 release, it has stopped
working. I need you to suggest an alternative, or fix the current
problem.

PLEASE NOTE: When posing a bid, please tell me if you have any experience with wordpress plugins and payment gateways.

Thanks for looking. Have a great day.
