Now I can’t login to wp admin, so I think I’ll have to go to cpanel to deactivate/delete the plugin. Great! * LE: Or I could wait for an update addressing this issue and then install it directly. Would that work? * [rowsdowr](https://wordpress.org/support/users/rowsdowr/) * (@rowsdowr) * [11 years, 11 months ago](https://wordpress.org/support/topic/error-line-55-56/#post-5002182) * @negue.c – I couldn’t get into admin after updating to the version released today( 6/12). I had to go into the plugins folder and rename the “better-wp-security” folder in order to regain access. * After I was back in wp-admin, I changed the folder back to its original name and reactivated the plugin. I went into iThemes settings and turned off the Hide Backend option. Now I can log in and out again. * Seems like “Hide Backend” is broken in version 4.2.10. At least for my site it is. * [iThemes Support](https://wordpress.org/support/users/ithemes-support/) * (@ithemes-support) * [11 years, 11 months ago](https://wordpress.org/support/topic/error-line-55-56/#post-5002185) * I just pushed a quick bump (4.2.11) to directly address the line 55 issue.
