sudden 500 errors

French, Shelane
Lasso 8.6 running on RHEL 6.9

This morning I came to work to find my server reporting 500 ISE errors. I have started up in console mode and I don’t see errors, but I do see it say “Claiming license instance #1” several times. I have a perpetual license, not a subscription.

Lasso Server Admin and Site Admin pages are running, but basic .lasso pages are not. I see no changes to the apache config files.

Re: sudden 500 errors

So I’ve traced it to this:

$__http_header__ += ' X-Frame-Options: DENY\r\n';

When this is in the code, I get a 500 error. Now it seems that the server admins must have changed something so that this is now a problem because until yesterday, it was working.

Remove the leading space from the header.

If that fails, see how to configure your web server to add that header.
