Dear,

I am getting so many "Cannot modify header information - headers ... " and some Table warning, it seems there had been something unusuall.

FYI here are the errors that I get:

Warning: Unknown column 'data' in 'field list' query: SELECT data, created, headers, expire, serialized FROM ishc_cache WHERE cid = 'variables' in /home/plastasia/domains/plastica.asia/public_html/dp/includes/database.mysql.inc on line 128

Any help would be appreciated

I am getting the same errors, so I'll post back here if I find the solution. This happened after I moved to a new host and transferred my database and files. I have another Drupal 6 site up and running with the same host and the same account, so I know that's not the problem.

In my case, I simply imported the wrong data into my new MySQL database (after switching hosts). I had to e-mail my previous host and beg them to send me a backup of the data. Luckily, Dreamhost is nice. With the right data, these errors went away for me.

I had to upgrade my development machine and thought I'd easily migrate all of my Drupal 6 sites. However, I cannot login to any one of my sites on the new machine, and if I play around with MySQL I get a fistful of errors if I try and write directly to one of the databases (desperate stuff, but I'm struggling).
Things I've looked at include:
- double checking I'd actually grabbed the right MySQL dump
- ensured MySQL can deal with both InnoDB and MyISAM tables (tweaking my.ini or my.cnf)
- giving loads of resources to PHP and MySQL (more memory, packet size, buffer size etc)

The sites I'm trying to access allow me to view a page as an unauthorized user. When I log in I just get sent back to the user/login page. Cannot run update.php (even with $update_free_access set to TRUE). And nothing is being entered into the watchdog table. Kinda feels like I have a read only database in my migrated set up... which is why I've been trying to add tables/data directly via MySQL. When I do try and add data I get the said MySQL errors:
Warning: Cannot modify header information...
So struggling here and would welcome a pointer from anyone who knows a little more about correct configuration of PHP/MySQL (a brand new OSX10.5 machine, having been unsuccessful with a Vista machine too)
