Important for those who upgraded from 5.8.5 to 5.9.3

[yuri]

Important. If you upgraded from 5.8.5 to 5.9.3 on June 22-23 and email sending stopped working is not working do the following:

1. Download 5.9.3 version from the site or Github.
2. Remove vendor folder from your EspoCRM instance.
3. Copy vendor folder from the downloaded package.

Hello Yuri.

in my experience.. i have install some package (sepaXml, phpWord, ftp.. ) and after some ugrade i have always problem and must copy vendor folder for some package.
maybe is the solution when upgrade :

first delete composer.lock and then do in upgrade ..

php composer.phar install --ignore-platform-reqs
php composer.phar dumpautoload -o 

for this moment, i have always problem with doctrine folder.. i replace from zip the folder .

There's is an ability to put vendor in module dir and specify it in autoload.json in the module.

If we don't have email sending problem we can ignore this right? Or should we still try to update/overwrite file? (version was from 5.9.2 > 5.9.3)

Yes. You can ignore. The problem can occur only if upgraded from 5.8.5 to 5.9.3 on June 22-23. If email sending is working, that means upgrade went well.

The problem was that upgrade package was built not fully.
