The page I need help with: http:///wp-admin/network/index.php Hi @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. Im not aware of any changes being made to lscache. Perhaps Ill have to inquire. When I go into settings and attempt to save, I get a white page with ONLY the following echoed out Warning: Illegal string offset version in /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php on line 598 Warning: array_keys() expects parameter 1 to be array, string given in /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php on line 539 Warning: array_diff(): Argument #2 is not an array in /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php on line 540 Warning: array_diff(): Argument #1 is not an array in /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php on line 548 Warning: Illegal string offset version in /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php on line 555 Warning: Illegal string offset mobileview_enabled in /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php on line 557 Warning: Cannot modify header information ? headers already sent by (output started at /public_html/wp-content/plugins/litespeed-cache/includes/litespeed-cache-config.class.php:598) in /public_html/wp-includes/pluggable.php on line 1210 Did you try to delete the current plugin and install a new one? We just released v1.2.1 @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.
