Make sure your /usr/local/ioncube is not empty.
if its empty then unpack the content of https://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz in /usr/local/ioncube/
mike This is interesting. I have ioncube available there, but missing the lirary for php 8.4. I just uncompressed a fresh copy to fix that.
