Error 500: Error while rebuilding database. See log file for details.

What about Clear Cache and Rebuild after it..... But rebuild clears the cache as well...
What db driver do you use: mysql or mariadb? and version, please.

Ok, There is what I did:
I downloaded ESPOCRM 4.8.2 (it 's my current version) from source forge, extracted it, uploaded and replaced 'application' and 'client' folders (I don't have any other extensions installed). Then I deleted all folders in custom/Espo/Custom, now it is only .htaccess file left. Then I logged in, ran Rebuild, but still get the same error. what can be wrong? Should I replace all files and folders?

[tanya]

Here you can download your version https://sourceforge.net/projects/espocrm/files/
Extract zip, replace 'application' folder and 'client' folder (if you don't have any extension)
And if you want to delete all customization, made with Entity and Layout managers, you can also remove folders from custom/Espo/Custom
After that run Rebuild

where could i find this json file - I think you rename the field name in entityDefs of Account. so open your entityDefs/Account.json (custom or in Crm module)

Sorry, I meant I changed only value, not the name. Now i reset to default. I also found more customizations, so I reset hem to default, and one filed, which was created by me, deleted..where could i find this json file? Is the any way to reset everything to default?

[tanya]

Why do you modify the name? You could change the label.
Check if your json file is valid

I can't rebuild, I get the same error. I think, that I didn't modify the core file, only the name.

[tanya]

Can you run rebuild successfully? Just Rebuild, without Upgrade?
And did you modify any core file?

[sarunijus]

Well, actually I've tried to create custom fields earlier, but then I deleted them, so no new custom fields, But what I did, I renamed field sicCode to VAT number in Account fields. When you mention it, I also think that it can be related to that. But anyway, even If I had custom field, how then should I upgrade it? Many thanks.

[tanya]

Hello
Did you create any custom field manually? or installed any extensions?
Not sure, that it is related with upgrade.

[sarunijus]

Tanya, any ideas? I've checked out the forum, but didn't find a solution, which works.
