 * Hi [@luckyfox](https://wordpress.org/support/users/luckyfox/),
 * Looks like you are upgrading lscache. May I know what the previous version is?
 * Also, if you go to setting and save options, will the warning disappear?
 * Thanks.

 * I’m not aware of any changes being made to lscache. Perhaps I’ll have to inquire.
 * When I go into settings and attempt to save, I get a white page with ONLY the
   following echoed out;

 * Did you try to delete the current plugin and install a new one?
 * We just released v1.2.1

 * [@hailite](https://wordpress.org/support/users/hailite/) Updated, made no difference.
 * However, **_completely_** deleted and reinstalled it and it worked without incident.
 * Going to mark this as resolved and will reference if it returns in the future.
