 * Hi aboveNbelow,
 * This is strange behaviour. Can you send a screen shot? Which version of WP are
   you using?
 * Please feel free to email your WP login and FTP info to [help@time.ly](https://wordpress.org/support/topic/white-screen-fatal-error/help@time.ly?output_format=md)
   and we our support team may be able to install this for you / investigate the
   issue.

 * Wow, I’m also having this same issue! I just deleted Timely due to another issue
   I was having and re-installed it, now my it appears as if my website has vaporized,
   only to be replaced with an all white screen. I’m trying not to panic.

 * So, I upgraded to the premium for free and got my site back but the old bug has
   returned (event text appearing at the top of my browser window). I so wish this
   plugin would work.

 * Hi kschilling,
 * Glad to hear you got your site back by upgrading. Now, let’s try to troubleshoot
   the event text bug. So that we can rule out a theme or plugin conflict, please
   can you follow the steps on this link:

 * Hi Richard,
 * I too get the error and it has locked me out of my site: How do I manually uninstall
   this plugin so I can get my site back? Thank you.
 * student.lecomsga.com – this is the site with the problem
