I recently changed the name of the forum from the control panel (not the web address, just the name) and added the '%' symbol in the title — could that be a problem?

Remove your % symbol and see if it's fixed.

How can I delete the simbol if I can't open another page from the Control Panel because it opens a blank page?

 

[CedricV]

Can you reach the domain /admin.php?options/groups/basicBoard/ ?

Can you reach the domain /admin.php?options/groups/basicBoard/ ?

I can only access the first page of the control panel mywebsite.com/admin.php). Beyond that, whatever I select shows a blank page.

 

[CedricV]

Do you have access to your database?

Go to the xf_option table, search for the boardTitle row.

You should see something like:
option_value = Romania In %Rebuild (or whatever contains the %)

Remove the symbol, save the change.

I downloaded the binary file, removed the '%' symbol, modified the table in the database, but the problem still persists

Try rebuilding the master data via /install .
