500 error after upgrade to 6.12

[Bill in CA]

I am seeing intermittent errors when trying to create posts or add comments since I did the 6.12 upgrade. It looks like short posts are working but longer messages are causing errors.

1) I don't have any plug ins installed

2) I cleared cache in the control panel

3) I tried to use RECOVERY MODE but get this error message:

1S107/3 Before you are able to use the Admin Control Panel, you must edit 'constants.php' and remove the following line:

define( 'RECOVERY_MODE', TRUE );

4) Nothings is showing in the System Log or Error Log

5) Restored to default theme, no change

Any suggestions on where to look next?

Are you still experiencing the issue or were you able to resolve it?
I tried to reproduce the issue on your board by creating a really long topic and reply and didn't run into any error.

 

Looking at your system log, you were missing some database tables 6h ago?!
Was this related?

I did another clearing of cache not long before your test (thanks very much for doing those) and I haven't seen the problem since.

The database errors came up when I had upgraded to 6.11 earlier today, but seem to have stopped after I then did the 6.12 upgrade.

So, right now, fingers crossed, it looks like things may be working OK. I will see what happens more more uses start using it now that I've told them the upgrades are done.

Many thanks for the help and the promptness.

Oh - any idea why RECOVERY MODE didn't work? I put the line as the first entry in the constants.php file as shown in another post.

Oh, I also had run the background job to complete indexing.

recovery mode disables 3rd party items. If you have none, it wont actually be doing anything

OK, thanks for the info.
