Since a while I am trying to replicate the SellYorSaaS setup from the ground up on Ubuntu 20.04 hosted in the public cloud of OVH. I think I am now almost there, admin and myaccount pages are generally operational and I did successfully set up instances on the deployment server.
I will give feedback into the documentation as pull requests once I have a bit of time (apart from the fact that this is an excellent and very detailed example of great instructions) - there are some points, where I needed to slightly deviate from the written "truth".
One of the last points where I am struggling are some sub-pages on the myaccount page:
If I click on "my apps and options" or "add payment mode" nothing is shown apart from the error ERR_EMPTY_RESPONSE.
The apache error log shows:
[Tue Jul 19 18:53:48.485111 2022] [mpm_itk:error] [pid 634120] child died with signal 11
The last meaningful rows in the dolibar.log before the crash are:
2022-07-19 19:11:28 DEBUG 84.189.75.1 sql=SELECT DISTINCT r.module, r.perms, r.subperms FROM llx_usergroup_rights as gr, llx_usergroup_user as gu, llx_rights_def as r WHERE r.id = gr.fk_id AND gr.entity = 1 AND gu.entity IN (0,1) AND r.entity = 1 AND gr.fk_usergroup = gu.fk_usergroup AND gu.fk_user = 2 AND r.perms IS NOT NULL
2022-07-19 19:11:28 NOTICE 84.189.75.1 --- Access to GET /index.php - action=, massaction=
2022-07-19 19:11:28 DEBUG 84.189.75.1 sql=SELECT transkey, transvalue FROM llx_overwrite_trans where lang='de_DE' OR lang IS NULL AND entity IN (0, 1) ORDER BY lang DESC
Everything else under myaccount works as expected (show/modify account, show invoices etc.).
Furthermore, I am sure that I have seen the now non-working pages after the creation of the first instance. So some later data leads probably to a crash in whatever sub task is called to fetch some data.
I am a bit stuck here regarding further debugging and any hint would be much appreciated. It may well be a configuration error from my side rather than a real bug.
