What about bootstrapper repair?

 

[AntonKou]

Thank you for your quick reply. Do you have a ' How To' link to do that safely?

 

[IgorG]

Just try to use forum search engine. Bootstrapper repair procedure has been mentioned here a lot of times.

 

[AntonKou]

I've run

/usr/local/psa/bootstrapper/pp10.13.4-bootstrapper/bootstrapper.sh repair

successful.

Unfortunately the problem is still there.

I don't know if there is an correlation but another 'error' in /var/log/sw-cp-server/error_log is:

Are there any other suggestions?
Would an update to 11.0.9 fix this issue?

Thank you in advance.

 

[IgorG]

In any case upgrade to latest available version is better solution.

 

[AntonKou]

Could the error 'PHP Fatal error: Class 'Service_Agent' not found in' be a problem during the update to PP11 ?

 

[AntonKou]

Update to PP 11.0.9 fix the problem.
