How critical was the error when updating?
Hi @weddingtextile,
Can you please provide us the log of your upgrade? It can be found in the log.txt file, available in
Thanks!
Hi @weddingtextile,
Thanks for your feedback.
I did not manage to reproduce the issue, I made an upfrade from 1.7.3.3 to 1.7.4.3 with the 1-click upgrade 4.4.0.

In your case, In your file log.txt, I found this:
Database upgrade OK
[2018-10-27 16:11:10] [SKIP] directory "/app/cache/" does not exist and cannot be emptied.
[2018-10-27 16:11:16] Warning detected during upgrade.
[2018-10-27 16:11:16] Database upgraded. Now upgrading your Addons modules...
[2018-10-27 17:11:16] Addons modules files have been upgraded.
[2018-10-27 17:11:16] The database has been cleaned.
So the upgrade is done successfully.
In your error_ul14_apache_aux1_18-10-27.log file,
Sometimes when migrating sites are switching between mod_php and FCGId permissions can get mangled which cause errors such as:
(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
when running in FCGId mode.
Here's a solution to be ass follows.
chattr -i php5.fcgiPS: for more details about this issue, you need to check it with your host.
About the javascript console log: this is a different issue fixed in this PR: #10684
Could you please try to clear cache manually by deleting all the folder into var/cache (prod & dev).
Thanks to check and feedback.
Thanks for the detailed answer.
One more question.
Is it normal after upgrade? See VERSION COMPARISON.txt
VERSION COMPARISON.txt
@weddingtextile, yes, it is normal.
I have changes in my case also.

Thanks!
Always use local directory upgrade mode with unpacked prestsahop files copied in autoupgrade/latest folder. I have done this version upgrade without any problem (1.7.3.3 to 1.7.4.3).
Hi @weddingtextile,
Since we had no news from you for more than 30 days, I'll close this ticket. Feel free to open another one if you can give specific details.
Thanks!
when i had problem to update my prestashop, it was because a module cause problem
try to desinstall the modules you installed one by one, and try to update after each desinstall
