Since this entry is considered “resolved”, I’m inquiring on the Piklist forum instead. Thanks,

I have the same problem (blank page w/ HTTP 500 Internal Server Error).
However, I don’t use WordPress’s FTP feature. I deleted the old plugin via command line and then got the new version using wget.
After I enable the plugin, http://mywordpress_website_FQDN/wp-admin becomes inaccessible (until I delete entire Piklist plugin folder).
Can you please advise?
Thanks,
