These and similar errors immediately after an upgrade are usually caused by one of two things:
- Old plugins that haven’t been updated to work with the current version of Textpattern
- Not updating or uploading all of Textpattern’s files correctly. Make sure you upload all the files in all subdirectories.
Similar errors immediately after installation usually indicate:
- An incorrect
txpathsetting in config.php. The value automatically detected by the setup process is almost always correct, so don’t change it unless you know what you’re doing.
- Textpattern .php files that are missing or in the wrong location.
