Question

MODX

In the Modx Evolution admin panel, when clicking on some snippet, the following error appears:
clip2net.com/s/3BEZTK2
Warning: include_once(actions/mutate_snippet.dynamic.php) [function.include-once]: failed to open stream: No such file or directory in /home/data/www/v/vipsystems.ru/docs/manager/index.php on line 465
Warning: include_once() [function.include]: Failed opening 'actions/mutate_snippet.dynamic.php' for inclusion ( include_path='.:/home/data/www/v/vipsystems.ru/lib:/usr/share/php:/home/data/www/v/vipsystems.ru/docs/manager/includes/') in / home/data/www/v/vipsystems.ru/docs/manager/index.php on line 465
Options?) Thank you!)

Answer 1

file exists, folder exists? check the permissions on the host, 755 for folders and 644 for files, run everything through filezilla. Once it was similar, the rights helped.
