Hi, it once happened to me and today again...
When I update the GF plugin, the page where WP shows the operations doesn't say "plugin reactivated". It stops and then I have a 500 Internal Error.
Last Time I had to reset the wp-option table and reconfigure the site, saving the posts.
This time it seems to have problems with my theme: but it iwas working fine before I tried to update the plugin! Is there anything I should check?
Thank you very much.
