If you run into an error or a blank (white) page when activating our theme, then most probably your hosting service is using an old version of PHP (5.2.x or lower).
Please contact your hosting company and ask them to update the PHP version of your site to at least 5.3.x, but we recommend version 5.6.x.
In the majority of cases, you will get a blank (white) page and no errors, but the problem is the same. The error is still there, but it’s just not displayed.
Example of the error when activating the theme:
Warning: require_once(__DIR__/composer/autoload_real.php) [function.require-once]: failed to open stream: No such file or directory in .../wp-content/themes/repairpress-pt/vendor/autoload.php on line 5 Fatal error: require_once() [function.require]: Failed opening required '__DIR__/composer/autoload_real.php' (include_path='.:/usr/local/php5/lib/php') in .../wp-content/themes/repairpress-pt/vendor/autoload.php on line 5
