对 .htaccess 文件的更改不断使我的 Wordpress 站点崩溃

Question

A while ago, I started having a problem where every few days, my Wordpress site would crash. Instead of loading, the site would just download the contents of index.php.

After some investigation, I found that commenting out the following line in the .htaccess file solved the issue:

AddHandler application/php-70 .php

However, my comment on that line keeps getting over-written somehow.

So here are my questions:

• Why is that line causing the issue, and can the root cause be addressed?
• If the root cause can't be addressed, how can I prevent my comment on that line from being overwritten?
• If I can't prevent the comment from being overwritten, can I add some sort of monitoring to show my what's causing changes to the .htaccess file?

Seems like some plugin is overwriting your changes in .htaccess, check this link https://wordpress.org/support/topic/php-version-change-can-break-htaccess which addresses a similar problem.

Also, you can follow the instructions here https://www.siteground.com/kb/how_to_have_different_php_versions/ and you should (if you can) change/upgrade your php version to the required version.

Alternately, you can chmod 655 .htaccess file to disable any plugins writing to it.
