I am having the same problem. What I did was comment out the "getsectionname" call and the "getpermissions" call and now the header tag button opens and I am able to enter my tags. However, I got a new problem now when I try to go to the catalog button. It opens and so far, I can navagate through it, but I get the following message across the top of the screen:
G_IMAGE_DIRECTORY_NOT_WRITEABLE', 'Error: Catalog images directory is not writeable: ' . DIR_FS_CATALOG_IMAGES); define('ERROR_CATALOG_IMAGE_DIRECTORY_DOES_NOT_EXIST', 'Error: Catalog images directory does not exist: ' . DIR_FS_CATALOG_IMAGES); define('ERROR_CANNOT_MOVE_CATEGORY_TO_PARENT', 'Error: Category cannot be moved into child category.'); ?>
I am not a PHP programmer or even literate with PHP, but I've figured out my way around this so far and wanted to know if anyone has seen this before or can let me know where to look to fix it.
Thanks!!
