UpgradeModx: No older versions shown than 2.6.1 - despite of versionsToShow setting 10

I have to upgrade an older Revo site of a new client who just came to me. He has MODX 2.3.3 site running.

I'd like to upgrade to 2.4 and 2.5 before going to 2.6.0 and 2.6.5 - Bob Ray gave that advise in the Upgrade/missing-db-fields article.

I changed the snippet property "versionsToShow" to 10, saved, cleared the cache, went to dashboard and then hit UpgradeModx - but there still are only the versions from 2.6.1 to 2.6.5 shown. Tried several times, also with fresh browser cache. I'm using UpgradeMODX 1.5.5.

Seems I'm missing something - Thanks again for your help!

Clearing the cache doesn't always do it.

Try manually deleting all files in the core/cache directory.

FYI, the next version of UGM will solve this by automatically extending the version list to include your current version.
