IPB 3.4.x unable to save settings

[rev.dennis]

I know this version is no longer supported and we are working on upgrading our applications to support IPB 4.  No emails are being sent out so trying to update from PHP to SMTP but anytime I click save it goes back to the original..  it doesn't save any settings.

I have also tried to update someones password and it won't let me.

I have tried to use Chrome and Safari, I have cleared all cookies and cache and tried and really just out of ideas.

We do not use friendly URLs (so no .htaccess file).....

It says Settings saved but nothing changes.. it reverts back to what it was.  Doesn't matter if its Email or SEO settings...  the system just will not allow anything new to be saved.

I tried to change my php setting from /var/cpanel/php/sessions/ea-php56 to /tmp thinking it might be an issue but no difference.

I look at the error log under admin directory and I see things like

Any ideas?

I tried changing save to /tmp and no luck then I started to look at some of my other sites and most settings were same but memory and file upload sizes were different so I decided to just copy the php.ini from working site and paste to broken sites and they all started to work.

Working php.ini for me for IPB 3.4.x

session.gc_maxlifetime = 1440
session.save_path = "/var/cpanel/php/sessions/ea-php56"
upload_max_filesize = 20M
zlib.output_compression = Off

Once this was pasted into each broken site I was able to save settings once again.
