Deleting Decorators - You do not have sufficient permissions to access this page.

[Graeme Morris]

I recently discovered an error. I tried to delete a decorator and it gave me the error 'You do not have sufficient permissions to access this page'

Here is how I solved it: 

You have to change the delete path in the WPSimileTimelineAdmin.class.php
Step 1 Find '/plugins/wp-simile-timeline/inc'
Step 2 Edit 'WPSimileTimelineAdmin.class.php'
Step 3 Do a search for 'stl-delete-decorator'
Step 4 Replace 'options-general.php?page=timeline.php&action=delete-' with 'admin.php?page=wp-simile-timeline&action=delete-'
Step 5 Save and upload back to '/plugins/wp-simile-timeline/inc'

Hope this helps.
