 * I have WP 7.0, PHP 8.4 LC 7.8.1, litespeed 6.3.5
   where I have export settings
   at /wp-admin/admin.php?page=litespeed-toolbox#import_exportThen i went to other
   site on same server with same versions (except PHP is 8.5 using CLoudlinux PHP
   selector) and import mentioned file. It result in error: [https://justpaste.it/2p3zm](https://justpaste.it/2p3zm)
 * The error disappear after resetting settings at same #import_export page. But
   i want to have same settings as on other site and the import should not end up
   with user unfriendly error?
 * export file cross-site differences at least this:
 *     ```wp-block-code
       ["cdn-ori",["\/\/sub.domain.name\/"]]["object-host","\/home\/usernamehere\/.redis\/redis.sock"]
       ```
   
 * but adjusting these before import, still fails. I can modify and re-save these
   values at:
   /wp-admin/admin.php?page=litespeed-cache#object/wp-admin/admin.php?
   page=litespeed-cdn#other
 * after such action, i think that i have reasonably same litespeed settings after
   import and [this is LS sys. info](https://justpaste.it/8ey4v).
 * maybe you can make LC automatically adjust these site specific values like username
   and site address post-import.

 * [@postcd](https://wordpress.org/support/users/postcd/) we are sorry for inconvenient.
   The error will be fixed in next version.
   Until then I would disable OC in import
   settings(leave the rest as they are or change what you need) then enable it manually.
