# Warning

 * I have the plugin installed on a fresh install (no other changes or plugins installed).
   I’ve got ‘Twitter Bootstrap CSS v3.0.2’ enabled in the settings. The only other
   box in the plugin settings that I’ve got checked is: ‘Enable LESS compiler section’.
 * I saved the settings and it looks like it saves just fine. But when I switch 
   to the Bootstrap LESS section and I get the warning below:
 * Warning: copy(…/wp-content/plugins/wordpress-bootstrap-css/resources/bootstrap-
   3.0.2/less/variables.less.orig) [function.copy]: failed to open stream: No such
   file or directory in …/wp-content/plugins/wordpress-bootstrap-css/src/hlt-bootstrap-
   less-base.php on line 63
 * The Bootstrap LESS page takes forever to load and nearly brings Chrome to its
   knees.
 * Any suggestions?

 * Hey Shawn,
 * Sorry about this… there was a bug introduced in the latest release and should
   now be fixed in v3.0.2-2.
 * Cheers,
    Paul.

 * As to the slowdown, I’ve experienced the same thing myself, but on Firefox (and
   also Chrome to a lesser degree).
 * Since nothing changed on this page, I figured something on the environment changed
   and I narrowed it down to my LastPass browser plugin which was updated to v3 
   recently. So you either have lastpass, or another browser plugin that is parsing
   all your input fields and that’s hanging your browser.
 * Hope that helps you track it down for you.
    Cheers, Paul.

 * I do have LastPass… interesting. Must be it on the page load time.
 * I updated to the new version. I’m not getting the warning error message that 
   I had before when loading the Bootstrap LESS page anymore.
 * Also, when saving my changes in the LESS page, it says that they were saved successfully(‘
   Updating Twitter Bootstrap Settings Succeeded.’), but I end up with 3 errors 
   listed:
 * lessphp fatal error: Failed to assign arg [@list](https://wordpress.org/support/users/list/):…/
   wp-content/plugins/wordpress-bootstrap-css/resources/bootstrap-3.0.2/less/bootstrap.
