Hi, we have taken note of your request to install a new extension, however for security reasons Miraheze reviews all new extensions to make sure that they are secure for use, so this will have to be done first.

• Semantic Result Formats does not work: Fatal error: Cannot redeclare smwfContLang() (previously declared in /srv/mediawiki/w/extensions/SemanticResultFormats/extensions/SemanticMediaWiki/includes/GlobalFunctions.php:28) in /srv/mediawiki/w/extensions/SemanticMediaWiki/includes/GlobalFunctions.php on line 27

I believe this is caused by an incompatibility with how composer is needed to be installed for the extension, which is incompatible with our setup of submodules.

Unfortunately, because of that, that extension can not be done.

All 3 extensions are approved, but also an issue with SemanticGlossary, which is again caused by incompatibilities with our composer setup.

• Error: Class 'SG\HookRegistry' not found

However, Semantic Forms Select does appear to work, so that can be approved/installed.

I may look into adjusting our composer setup eventually to support those other type of extensions, but for now they can not be installed. I apologise for the inconvenience.

Maybe this Hostinger support page has just the tip for how to fix it (but we can't quite be so sure yet):

This point can be fixed easily by using include_once instead of include when including your PHP file.

The submodules way we install extensions mean we can not edit extensions, the way MediaWiki also works, prevents us from modifying the way things load, so in this case, that will not work. The issue is because SMW is installed via submodule, but the extension tries to re-install and include it via composer, which leads to files being double loaded and thus not working.

As for Semantic Result Formats, customising it for Miraheze seems like the only viable alternative left, I assume.

To @Universal_Omega: After nearly a month's delay, I have brought the SRF issue here to the SMW team's attention at GitHub. Sitting back and waiting on further developments.
