Learn moreCommon problems¶
Check first:
- You followed all the directions on the Upgrading MODX page.
- You uploaded all the necessary files for the upgrade, merging directories instead of replacing them.
- You cleared your browser cache after upgrading. That clears up most JS and CSS related errors.
- You cleared the site cache after upgrading. Setup does not always do it, depending on your environment.
Help! The only option I can choose is "New Installation", but this is an upgrade!¶
This occurs when you erase the core/config/config.inc.php file. Restore it: if you made a backup before upgrading, copy the file from there to your core/config/ directory and make it writable.
Without a backup, create a new core/config/config.inc.php from the template in core/docs/config.inc.tpl, replace all the placeholders surrounded by {}, and make the file writable.
Setup went well, but my manager isn't fully working¶
Clear your browser cache: the browser caches manager JS and CSS for speed and keeps using the old files after an upgrade. Since 2.0.2 this is rarer, because manager assets carry a cache-busting query token, ?mv=<adler32 hash of version + uuid>, that changes after every upgrade.
On MODX 3.x the Manager ships prebuilt asset bundles. There is no manager/min/ compressor path anymore (removed in 3.0). If a page looks blank after upgrade, clear the browser cache for the manager host and confirm your Extra still loads its own assets under assets/components/<namespace>/ (its PHP lives in core/components/<namespace>/).
