ubuntu – Finding the worpress installation log refers to

Today, I had

    A total of 2 possible successful probes have been detected (the following URLs
contains strings that match at least one string list
indicate a possible feat):

/wp-content/plugins/wptf-image-gallery/lib-mbox/ajax_load.php?url=../../../../../wp-config.php HTTP 301 response
/wp-content/themes/mTheme-Unus/css/css.php?files=../../../../wp-config.php HTTP 301 response 

from Logwatch.

I did find / -name wptf-image-gallery -type d on my server to remove it but there was no result.

What should I do now? How to find the relevant wordpress installation?
