Failed loading Zend extension

Hi everyone, I'm having the following error message show up in the error log of every one of my folders whenever I run a PHP file. So as a result, some of the error logs are getting quite large.

PHP Warning: Failed loading Zend extension '' (tried: /opt/imh/imh-php72/root/usr/lib/php/extensions/no-debug-non-zts-20170718/ (/opt/imh/imh-php72/root/usr/lib/php/extensions/no-debug-non-zts-20170718/: cannot read file data: Is a directory), /opt/imh/imh-php72/root/usr/lib/php/extensions/no-debug-non-zts-20170718/.so (/opt/imh/imh-php72/root/usr/lib/php/extensions/no-debug-non-zts-20170718/.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I am running PHP 7.2.19

Here are a few lines from my php.ini file that may be of help:

; The directory under which PHP opens the script using /~username used only
; if nonempty.
user_dir =

; Directory in which the loadable extensions (modules) reside.
extension_dir = "/opt/imh/imh-php72/root/usr/lib/php/extensions/no-debug-non-zts-20170718"

;zend_extension = "/opt/php54/lib/php/extensions/no-debug-non-zts-20100525/ioncube_loader_lin_5.4.so"
zend_extension_ts=""
;extension=homeloader.so

At the very bottom of the php.ini file is this:

[Zend]

zend_extension =

Hopefully someone can help me sort this out. Thanks very much in advance.
