Failed to load resource error after migration to new domain


I just transfered my website from my testserver to the live server with the help of snapshots and now I get the following error in the console and the arrows in my portfolio are not displayed anymore. usually they have an image as background, but they seem to not have one now… (the theme ist the7)

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

…./css/less/filter-&-pagination.less Failed to load resource: the server responded with a status of 500 (Internal Server Error)

You can see the error on this screenshot:

And the website with the problem is here:

Do you know what the source of this problem could be?

    Hi ,

    There are few reasons for Internal Error 500, you can read about this here

    But, the error is related to the less file – and if there is no arrows where they should be it it means that there is no arrows in the css style files. Do you know if the css files of the theme were generated “on the fly” on your testing environment?

    Kind regards,

    Hi flobrunner,

    Does your test sever have the same parameters as the live one? If the less files are processed on the fly maybe there is problem with resources with your live server?

    Please, enable the debug mode in WordPress maybe there will be answer. To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

    ‘define(‘WP_DEBUG’, true);’

    In order to enable the error logging to a file on the server you need to add yet one more similar line:

    ‘define( ‘WP_DEBUG_LOG’, true );’

    In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

    Depending on whether you want your errors to be only logged or also displayed on the screen you should also have this line there, immediately after the line mentioned above:

    ‘define( ‘WP_DEBUG_DISPLAY’, true );’

    The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it.

    Kind regards,
