Hi,
Thanks for your feedback. Unfortunate i’am not able to replicate the issue on this side, can you send some more details? When exactly you see this error? What server type you run? From what plugin version you updated?

Thanks

You must be using FS_METHOD and “ssh2”, “ftpext”, or “ftpsockets” not “direct”
Can you confirm this is fixed in Version: 1.5.6.7 ?

Thanks

Yeah I had that documentations, but I had a problem with webhost as well to configure FS_METHOD.
Plugin is working very well for me now.

For ppl who would have that problem, the easiest way is set FS_METHOD as ftpext.
Add this on end of wp-config.php file
```
/** FTP Connection - manually added **/
define( 'FS_METHOD', 'ftpext' );
define( 'FTP_USER', 'user' );
define( 'FTP_PASS', 'pass' );
define( 'FTP_HOST', 'hostname' ); //usually localhost:21
define( 'FTP_SSL', true ); //if you have ftp with ssl leave it true
```
You should be able to install plugins successfully now.

For linux issues:
Next problem which you can meet is that plugin will give you errors and asking about writable directories and if you are sure that all directories of wordpress has permission is 755 and files permission is 644 then you need to change owner of whole wordpress to user who run your webserver process.

chown -R httpd /path/to/web/wordpress

The user ‘httpd’ can be different for you.

Hope it helps.

Regards and thanks for helping me with plugin 🙂

Confirming that 1.5.6.7 fixes the issue.
Just a note – we do not use FS_METHOD = direct (default) it’s not changed anywhere.

On one site, I have the following error

Zend OPcache API is restricted by “restrict_api” configuration directive in …/wp-content/plugins/wp-hide-security-enhancer/include/functions.class.php on line 2476

On another site, I have:

@pidho1 Thanks for your feedback.

1) For the first site, it appear the opcache() is restricted from your server settings. Is this show as a notice, warning or an error?

2) This is strange, let me check further into this and i’ll come back with an update.

Thanks
