There are pages in my site which can be edited normally, but on some pages there is only white screen when trying to edit them. If I deactivate Toolset Blocks, everything works as expected.

Debugging is on and there are lots of memory and resources assigned to this site. Still I can't figure out how to correct this.

A white screen means a fatal error on the server, so you should check you debug logs for details.

If you haven't already, turn on the debug log by editing your wp-config.php file and change the line with WP_DEBUG like so:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
define('WP_DISABLE_FATAL_ERROR_HANDLER',true);

That will create a debug.log file in your /wp-content/ directory which you can examine in any text editor. Try visiting the same pages where you observe the problem and then inspect the log.

Let us know what you find, the errors should help identify the problem.

Yes this I have done already and only error there is like this:

[06-May-2022 06:58:41 UTC] PHP Notice: Trying to access array offset on value of type bool in /var/www/vhosts/o.tyonalla.fi/httpdocs/wp-content/plugins/wp-smartcrop/wp-smartcrop.php on line 413

Anyway I have already deleted this wp-smartcrop plugin completely, white screen stays and no errors, so no help there.

Hello,

Is there any JS errors in your website? you can get the JS debug logs by following our document:
https://toolset.com/documentation/programmer-reference/debugging-sites-built-with-toolset/#javascript-debugging
section "Javascript Debugging"

If the problem still persists, please a copy of your website in below private message box, you can put the package files in your own google drive disk, share the link only, also point out the problem page URL, I need to test and debug it in my localhost, thanks

Yes there are errors, in Safari dev (see attachement). Would it be possible to give login access to site? It's is a dev copy already, the production site is elsewhere.

Please provide your staging website credentials + FTP access in below private message box, I might need to deactivate plugins/theme in your website, please backup your website first.

It should be a known issue, see our erratum:
https://toolset.com/errata/errors-when-using-3rd-party-blocks-with-dynamic-sources-since-wp-5-9-update/
Please try the workaround of above erratum, since the FTP access you provided above isn't valid, I get below error message:

Error: Connection timed out after 20 seconds of inactivity
Error: Failed to retrieve directory listing

you need to try to edit the wp-config.php file yourself.
