function add_option from Alex Stapleton is buggy on 5.0.4

[hgurol]

Its a very fresh installation of 2.2 with NO plugins and with the default theme, running on w2k3(iis6), mySql 4.1 and php 5.0.4.

While Im surfing on the admin area, posting or deleting pages, browsing the categories I recieve the below error message. Refreshing the page sometimes solve the problem but mostly it doesnt.

"Fatal error: Cannot unset string offsets in D:\...\...\www\wp-includes\functions.php on line 360 "

I open the functions.php file and go to line 360. I point the "function add_option" remarked as " thx Alex Stapleton,  http://alex.vort-x.net/blog/". I change this function with the version from previous version 2.1.3. And the problem is gone.

I dont know what the real problem is but feeling about a php version issue. I can provide more tests, information or screenshots if needed.

Make sure notoptions is an array before unsetting

Try that patch.

Replying to ryan:

Try that patch.

Ryan, that patch works fine for me. thx

(In [5500]) Check if is_array before unsetting array index. fixes #4306
