Lost connection to MySQL server during query

This error is probably not caused by b2evolution, try asking hosting support about it.

Thanks, I already commented out those lines. Regarding the MySQL errors, here is part of what BlueHost (My hosting provider) responded to me with:

Even the MySQL issues seem to stem from the odd manner in which it appears to be attempting to keep the connections open, there doesn't seem to be any adverse effects in spite of the messages.

Any ideas on these connection warnings?[/i]

Do you still get mysql errors after you fixed b2evo errors?

Your mysql is configured to close connection after 60 seconds, and it displays an error when it closes timed-out connection. b2evolution doesn't hold connections for that long, do you have any third-party plugins or skins installed? What pages do you get the errors on, I haven't seen any browsing your website.

I've got the same mysql error on all my public pages after upgrade 3.3.3 > 4.0.3

Lost connection to MySQL server during query(Errno=2013)

No errors during upgrade install. Site is http://apfrod.com

Try to apply the fix I mentioned in the above post.

I'm getting the following error in comments:

Notice: Undefined index: makelink in /home/mitup2/public_html/b/plugins/basic_antispam_plugin/_basic_antispam.plugin.php on line 214

Ideas?

@sam2kb thanks, your solution worked.

Hmmm, I use Bluehost as well but didn't have any of these errors with my upgrade (I went from 3.x to 4.0.3). If you want to compare setups let me know.

I upgraded yesterday from 3.3.3. to 4.0.3 and was experiencing the same as described by dadefan in their opening post.

I applied the comment out fix supplied by sam2kb, linked to in their above post, but unfortunately I then received the follwing message and the site doesn't load;

Parse error: syntax error, unexpected '=', expecting ')' in /mnt/web2/23/43/5676443/htdocs/andyp/inc/_core/_misc.funcs.php on line 538

Should it be relevant; In my copy of misc.funcs.php the text lines were 142-167 rather than 145-170. I commented out the text block as shown in the fix.

I have rolled back to the version with the errors mentioned in the opening post, any ideas?

edit for clarity
