    Hi,
    Sadly I got a fatal error after removing some standard LESS variables in the wordpress admin. I wanted to leave some variables emty, but after that I can’t log into admin anymore.

    What can I do to fix this?

    Fatal error: Uncaught exception ‘Less_Exception_Compiler’ with message ‘Operation on an invalid type’ in C:\xampp\htdocs\website-link\wp-content\plugins\wordpress-bootstrap-css\inc\Less.php\Tree\Operation.php:45 Stack trace: #0 C:\xampp\htdocs\website-link\wp-content\plugins\wordpress-bootstrap-css\inc\Less.php\Tree\Expression.php(52): Less_Tree_Operation->compile(Object(Less_Environment)) #1 C:\xampp\htdocs\website-link\wp-content\plugins\wordpress-bootstrap-css\inc\Less.php\Tree\Call.php(45): Less_Tree_Expression->compile(Object(Less_Environment)) #2 C:\xampp\htdocs\website-link\wp-content\plugins\wordpress-bootstrap-css\inc\Less.php\Tree\Expression.php(52): Less_Tree_Call->compile(Object(Less_Environment)) #3 C:\xampp\htdocs\website-link\wp-content\plugins\wordpress-bootstrap-css\inc\Less.php\Tree\Value.php(27): Less_Tree_Expression->compile(Object(Less_Environment)) #4 C:\xam in C:\xampp\htdocs\website-link\wp-content\plugins\wordpress-bootstrap-css\inc\Less.php\Tree\Operation.php on line 45

    More details:
    I use the plugin: wordpress-bootstrap-css.3.3.5-0

    It looks like you’re running it locally there… just rename/delete the plugin folder to disable it and let you log back in.

    thanks for the response Paul.
    Indeed locally.

    I tried to remove the folder, to reinstall the plugin.
    But after installing it, the error pops up again.

    It seems like this is the problem:
    Because I removed a couple of variables, emty variables keep on coming in the variables.less file, like this:
    @body-bg: ;

    When I manually fill in the variables.less, it updates again to emty..

    Do you perhaps know the solution?
    So the variables in variables.less won’t turn up emty.
    I can’t go back into the admin to fill in the variables, bacause of the error.

    Thanks!

    Can you try setting the permissions of the file to read only so it doesn’t get overwritten? That might cause other errors, but worth a shot.

    That did the trick, thanks so much for your help Paul!
    I’ve been busy with this problem for hours now.
    Because I changed the file to read-only, I was able to change the variable values in the WP admin > LESS again, without being blocked by the error.

    Keep up the good work ??

    Great! I’ll look at somehow catching that error in the future.

    Thanks for working through it. Would you mind leaving us a review for the plugin? ??

    Thanks!
