So I was upgrading MW from 1.39 to 1.40 and following the guide here and here, I set $wgReadOnly in the LocalSettings.php, all things good, after completing the upgrade I started checking some of the pages for content and forgot to delete $wgReadOnly from config.
When trying to edit a page with VisualEditor, I was getting this error: Unable to fetch Parsoid HTML
I was sure this was an upgrade issue but it turns out that deleting the property is the fix.
Installed software
| Product | Version |
|---|---|
| MediaWiki | 1.40.1 |
| PHP | 8.1.14 (fpm-fcgi) |
| ICU | 67.1 |
| MariaDB | 10.6.11-MariaDB-1:10.6.11+maria~ubu2204 |
| Lua | 5.1.5 |
| Pygments | 2.11.2 |
- In MW 1.39, VisualEditor still works when $wgReadOnly is set.
Cheers
