I've brought up an issue on https://phabricator.wikimedia.org/T249988 that has yet to receive any possible solutions. Ever since I updated to 1.34 and applied the patch:
git pull "https://gerrit.wikimedia.org/r/mediawiki/extensions/Translate" refs/changes/81/560081/2
I've had issues on several translations. For example Tagalog is showing an internal server error that appears to have something to do with the l10n_cache table (full error available under the phabricator link). And Brazilian Portuguese articles are unable to show the latest revision after being updated (blank page is shown instead).
Could the patch have messed up something in my database? Or what could be causing these errors? I'd really appreciate a solution. (I've tried truncating the l10n_cache table, that didn't do anything).
