Ok I am not sure why I was unable to use FTP before, but I was able to find SFTP information in the control panel and I was able to log in using SFTP. Port :5544 is required for SFTP, so anytime someone from Toolset asks for that information please let them know it is required to use the port.
You can find the error_log file for your server by logging in to SFTP, then going to /log/
The error log file is around 16M. Most of the errors for the handball site are memory-related:
[Mon Jun 08 11:49:55 2020] [error] [client 62.203.26.6] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 532480 bytes) in /path/to/site/wp-content/plugins/wp-views/embedded/inc/wpv-filter-query.php on line 812, referer: <em><u>versteckter Link</u></em>

[Mon Jun 08 21:31:50 2020] [error] [client 157.55.39.110] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /path/to/site/wp-includes/meta.php on line 964
It looks like your default setting for memory was only 126M, so I have increased it to 256M (see below).
I also see a custom code warning, you might want to fix this:
[Mon Jun 08 12:02:20 2020] [error] [client 62.203.26.6] PHP Warning: Division by zero in /path/to/site/wp-content/toolset-customizations/automatischprozenteintragen.php on line 9, referer: <em><u>versteckter Link</u></em>
There were some syntax errors as well from someone editing wp-config.php. The WP_MEMORY_LIMIT setting in your wp-config.php file was added too low in the document, so I moved it up above "That's all, stop editing!". This is the proper location for the setting in wp-config.php, and now the site seems to be working correctly without triggering memory errors. Can you check the site now?
If you want to edit wp-config.php, please be sure you download the latest version from the server first.
Looks good so far.
1. Do I have too little space from the hoster?
2. What exactly do I have to do so that my page no longer has any errors?
I thank you very much for the great support. This is exactly why I have Toolset advertising on the website
1. Do I have too little space from the hoster?
I'm not sure about the amount of available disk space. I don't read German so I can't understand much in the control panel. I suggest asking your host company to find out how much disk space you have available, and then determine how much space you need to accommodate your future site updates.
2. What exactly do I have to do so that my page no longer has any errors?
The only error I have investigated in this ticket is the memory error, since it was directly related to the problem you described where some information is not displayed in some posts. The change I made in wp-config.php has solved this error permanently, and there is nothing else you need to do to solve this error. If you would like to investigate other Toolset-related errors, feel free to open a separate ticket for each Toolset-related error and we can investigate the cause and come up with a good solution. Most of the 16M messages in this file are not related to Toolset, and are not related to this site. Several other sites on this server are reported in the same log file.
