Hi

Are there any more tips for this.

This drama is mine now :D

I have changed from uikit to astroid and altered stuff in db (only tables relating to seblod)
I was on php v7.1.29, read that it was near end of life, so thought cool, I will go to 7.3 (after asking on Forum if was ok to do so), and now can only use 7.0

Warning: array_key_exists() expects parameter 2 to be array, null given in
/public_html/libraries/cms.php on line 74
Error: Failed to start application: Failed to start the session because headers have already been sent by /public_html/libraries/cms.php" at line 74.

Hopefully someone could suggest a few places to look

Thanks

Jon

Make sure that the save.session.path is writeable. The folder will change when changing php version.

wow, quick response. Thanks folks.

I edited the css classes within the db in the table:
#__cck_core_fields
#__cck_core_search
#__cck_sore_type

I am very comfortable editing these, in fact do it all the time (for years) as a shortcut :D

I will do the forum post assistant but struggling with that at the minute.
Can upload it, can delete it, but can't see any instructions on how to actually generate the info, unless I copy and past form the browser?

Following on from this:
Failed to start the session because headers have already been sent by "/home/sites/4b/3/30112786da/public_html/index.php

Code: Select all

https://forum.joomla.org/viewtopic.php?f=706&t=959704&p=3570949#p3570949
My error message was:
Warning: array_key_exists() expects parameter 2 to be array, null given in
/public_html/libraries/cms.php on line 74
Error: Failed to start application: Failed to start the session because headers have already been sent by /public_html/libraries/cms.php" at line 74.

I had increased max_input_vars from 1000 to 3000 using php.ini file
I had upgraded php from 7.1 to 7.3.
System threw up errors.
I went back to 7.1 and saw some errors, but Siteground suggested I use 5.6 and as a result I only receive a few errors.

I must have done something!!!

Is Joomla and all the third party extensions up to date?

today i will turn off plugins etc and see what gives....

Hmmm,

I have disabled all 3rd party extensions except seblod's (as there a bucket load of them!!).
AND
I have removed all data form .htaccess

The page loads without error - smokin'!!

So, it is between .htaccess and an extension me thinks.

Classic problem
Feel like I am edging towards a solution - nice!!

So

Found what seems to be the problem:
I had an out of date extension.
Such a classic problem, sorry to get everyone involved, but thanks for the interest.
I am now on php7.3 and all seems to be cruisey.

OUT OF DATE EXTENSION was J!Dump.
Not sure if there is a 'current' version compatible with php7.3....

Occam's Razor or perhaps more accurately lex parsimoniae!
Glad you are sorted. Time to address the out of date extensions and session path :D

From your FPA
PHP Configuration :: Version: 7.0.33 | PHP API: cgi-fcgi | Session Path Writable: No |
This needs fixed. It's a server side setting usually.

Make sure that the save.session.path is writeable. The folder will change when changing php version.
