I recently created a WP theme using the WP blocks. I made some mods to the css, nothing too crazy, but now when I upload and activate the theme, I am getting a 500 server error. I did recently upgrade to Pinegrow 4.911. Is anyone having issues with the latest version of PG? ---

Without anymore details (hosting provider, transfer app and more …), I can only guess the transfer went wrong but I don’t see any particular relation with Pinegrow. ---

I use Dreamhost as the provider and FileZilla as the ftp app. There weren’t any failed transfers and I did a complete transfer of the exported Wordpress folder. ---

Maybe you should try to install the theme on a local setup first and check if the theme is ok. (that’s the standard way to proceed for a successful experience). see: [https://pinegrow.com/docs/wordpress/10-things-you-should-consider-before-starting-to-create-a-wordpress-theme-with-pinegrow-wp/](https://pinegrow.com/docs/wordpress/10-things-you-should-consider-before-starting-to-create-a-wordpress-theme-with-pinegrow-wp/) > **[500 Internal Server Error](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/500)** > > The HyperText Transfer Protocol (HTTP) 500 Internal Server Error server error response code indicates that the server encountered an unexpected condition that prevented it from fulfilling the request. ---

As eranoud posted in this thread, it is fairly easy and advisable to test locally first to make sure your themes work properly before dealing with the server issues. ---

Ok, so this weekend I tested on a local server and was able to figure out that I mistakenly put a hyphen in the theme slug name. I manually updated functions.php and replaced the hyphen with an underscore and the theme works. Now, the issue is, even though I changed the slug name in pinegrow, it must be cached somewhere because when I re-export the theme, it reverts back to the hyphenated name in functions.php. I tried the clear cache in the File menu, but that didn’t seem to work. Does anyone know how to correctly update the slug name for a theme? ---

@adinezza try temporarily moving the functions.php file to a different place outside of you export folder then re-export. This way a new functions.php file will be created instead of overwriting/updating existing functions.php Hope this helps.
