Summary of the issue you are facing:
The docker app won’t start, just gives this in the docker logs:
app_1 | Can’t start Nextcloud because the version of the data (
app_1 | Warning: Cannot load module “memcached” because required module “igbinary” is not loaded in Unknown on line 0
app_1 |
app_1 | Warning: Cannot load module “redis” because required module “igbinary” is not loaded in Unknown on line 0
app_1 | 32.0.2.2) is higher than the docker image version (
app_1 | Warning: Cannot load module “memcached” because required module “igbinary” is not loaded in Unknown on line 0
app_1 |
app_1 | Warning: Cannot load module “redis” because required module “igbinary” is not loaded in Unknown on line 0
app_1 | 32.0.3.2) and downgrading is not supported. Are you sure you have pulled the newest image version?

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
