超出磁盘配额使用率:错误日志是public_html /中最重的文件,但我不知道如何解决问题

I am having this error in the Error_log:

PHP Fatal error: Class 'W3TC\Util_Content' not found in /home/cabrioletrepuest/public_html/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-integration.php on line 1

This is for a cPanel website. I do not have too much knowledge regarding on how to solve this issue.

I think that there is a file that is being automatically generated, and thus, exceeding the Disk Quota Usage.

I would really appreciate if you could help me with this. Thank you very much!
