Seeing the following PHP notice after upgrading to 1.23.0rc0.
PHP Notice: unserialize(): Error at offset 0 of 8 bytes in .../w/includes/cache/LocalisationCache.php on line 1298
Always at that line number. The bytes changes:
Error at offset 0 of 27 bytes
Error at offset 0 of 11 bytes
Version: 1.23rc
Severity: normal
This bug continues to happen during runJobs.php dozens of times throughout the day using 1.23.0-rc.1.
Please try rebuilding your cache with php maintenance/rebuildLocalisationCache.php --force
It is probably corrupted somehow.
So I alternatively have just tried "rm -rf *" in my cache directory which destroys all existing ones and they automatically get recreated. That does not help. The files get rebuilt and I continue to get errors in runJobs.
Should that also fix it if it is corrupted?
Tentatively closing for lack of updates or other reports of the same issue. Please do reopen if this is still happening with latest version of MediaWiki.
