Manual update fail... Help me

[kleo]

I have updated the system from 8.3.6 to 8.4.2 manual.

Probably I did something wrong there, but all the calls were no longer visible and I could no longer log out of the system.

In order to restore the status of the, I uploaded the files de version 8.3.6 to the server via FTP and overwritten the existing files on the server with it.

Now I can see the calls again, I can log in and out of the system again. However, I see the following error message in the log file:

ERROR: (-1) Uncaught Exception ReflectionException: "Class "Espo\EntryPoints\SubscribeAgain" does not exist" at /---/application/Espo/Core/Utils/File/ClassMap.php line 170 :: /---/application/Espo/Core/Utils/File/ClassMap.php(170)

How to eliminate inches?

Try deleting data/cache/application.

Unfortunately, the error remained...

I use hosting and therefore I do not have the opportunity to update the system as recommended by you.
I probably did something wrong with the manual update, but now I won't be able to figure it out.

Maybe I can try the following:

1. install a completely new 8.4.2 system with a new database in the new directory

2. after successful installation of the system, change in the file config-internal.php access data to the old database.


Is this possible, or are the databases of versions 8.3.6 and 8.4.2 different in structure?

I don't think so if it's still the error from your previous post.

I recommend to consider this approach.

1. Install a web server locally.
2. Copy the Espo instance from the hosting to the local server. It will require copying files. Dumping database and then importing.
3. Upgrade via CLI.
4. Move files and database back to the hosting provider.

It's pretty trivial routine for a web developer or sys admin. Though can be challenging for a non-technical person.
