Hi folks

I know - it is not advisable to run such old version of Drupal as 6.x (and even 7.x for that matter) for so many reasons, most important of which are security.

But for those who have no choice for whatever reason, here is a very easy and quick way to make everything work.
(not sure about if you have some different custom, non-Drupal core modules, of course).

After my hosting provider forcefully upgraded PHP to at least 7.4, my Drupal 6.33 sites stopped working (blank page).

I am working at a place using Drupal CMS and in their Infinite wisdom, they decided to disable (remove) the "view source" button in the WYSIWYG input window for their content. But Now they'r realizing that when things shows upas "&" and non-breaking-space or there's a missed tag and a hyperlink runs on for a whole paragraph, they're unable to see it and edit it, because they can't view the source.

I'm trying to install drupal 6 site in order to access old backup, but I keep getting http error 500 when I try to run the installation script as usual. Does anyone has idea of how to get around this?

Once in a while node access breaks and only admins can see content, I have to click rebuild node access then it's ok, any ideas?

in the https://www.drupal.org/docs/7/upgrade-to-drupal-7/drupal-6-contributed-modules-that-are-in-drupal-7-core page, under "Modules that can be uninstalled from your D6 site prior to upgrade" list, the modules autoload, imageapi, jquery_ui, simpletest all have D7 version.
