LangDelete plugin
This plugin removes all of the language files that accumulate and bloat the size of the wiki. More of these are brought in with every update of the wiki and all of its plugins, so it's good to follow such updates with a fresh cleaning.
This operation is found on the Admin page under Additional plugins > Delete languages.
HârnWiki isn't currently interested in saving any but the default English files. Those are retained even if the en listing is removed from the input box, so a simple ctrl+A, Backspace is fine. Untick the simulate only checkbox and hit Start.
This is an old plugin, and development seems moribund. It is sensitive to the PHP version being used by the particular server installation. Not every version has been tried, but this is what has been found so far:
| PHP version | Result |
|---|---|
| 7.4.1 | Functions, but with lots of garbage on screen; Show Page button missing at the end. |
| 7.4.30 | Works fine. |
| 7.4.33 | Works fine. |
| 8.2.1 | Does not work. A proposed change could address the problem but has not been merged into the the master. |
