Installing problem

Joomla! version 3.9.21 is the current version. Your website is up-to-date.

Hi
When you install - you install package, which contains component, plugins and modules.
Go to admin panel.
Press Menu ->Extensions->Manage->Manage
Enter zh into filter field, press search.
You will see my part of extensions. Uninstall it if it exists.

I definitely don't understand why you can't install.
First installation doesn't execute ALTER TABLE scripts from update folder, it skips it.

And I can't understand why table prefix added to whole table instead of replacing #_ symbols in table

THANK YOU for your help Dima...

I have done that and find COM_ZHOSMMAP
Try to uninstall but get an error...
Warning
JFolder: :delete: Path is not a folder. Path: /home/cumbriat/public_html/administrator/components/com_zhosmmap

Component Uninstall: Can't uninstall. Please remove manually.

FTP to /home/cumbriat/public_html/administrator/components/
but no folder called com_zhosmmap
Again FTP to /home/cumbriat/public_html/components/
No folder...
very stange!

Yes, it is too hard to understand, because I check pure installation and it was OK.
Lets try to trick.
Go to MySQL panel, for example phpMyAdmin
Go to your database and do select
select * from demo_extensions t where t.element like '%zh%'

where demo - it is your table prefix

You'll find line for my extension, just delete it.

After that Manage will not show my extension. And try to install it again.

HA...
Went to cpanel-phpMyAdmin
Searched and found table
Deleted table
Tried to install and success!!!

THANK YOU again for your help!

I hope you delete row for extension, not dropped table at all
