If the issue still appears, read provided information below.

First, check your database, see the wp_xmt_twt table.
How many records/tweets are stored there?

You can also try to delete the cache.

Here's a quick update to fix the export issue.
Extract the attached file below and upload profile-export.php to your plugins/xhanch-my-twitter/misc.
You should be able to export your profile after replacing this file.

You can mail the exported profile file to admin@xhanch.com

Many thanks for the fast reply!

Thanks I will give that a go and get back to you.

'delete all stored tweets' takes the database table down to 19 rows.  I did that yesterday though and obviously it got up to over 1000 on its own.

RESULT: all 8 tweets display.

As I say though, all 8 were showing yesterday too, and only 1 today without any settings changed.

Its now at 4 tweets - no settings changes or buttons pressed (other than emptying the WC3 Cache to see an updated page).  38 total rows in the database now also!

Emptying the W3C cache again made no difference to number of displayed tweets or rows in the db - so that cant be related.

Also the export still doesn't work with a new plugin file - still a blank page.

These are my settings:

Perhaps its the 10 minutes setting that double up the database rows each fetch?!

I think I'm learning something.
Looks like your database is not successfully updated.

Check your wp_xmt_twt table again (see its structure).
Can you find acc_nme_twt_id index?
If not, you'll need to delete all tweets/empty that table.
Then, run/execute this SQL query:

alter table wp_xmt_twt add unique `acc_nme_twt_id` (`acc_nme`, `twt_id`)

The only indexes are:

Keyname                 Type Unique Packed Column Cardinality Collation Null Comment
PRIMARY                 BTREE Yes No id 114 A
acc_nme_index BTREE No No acc_nme 0 A
twt_id_index         BTREE No No twt_id 2 A
twt_index                 BTREE No No twt 2 A
twt_dtp_index         BTREE No No twt_dtp 2 A
twt_typ_index         BTREE No No twt_typ 0 A

its because my table names have a 'ga' prefix to them over standard (security change).  So you need to make your install/upgrade scripts dynamic depending on the table name.

No, you misunderstood.
The updater script is actually like this:

$sql = 'alter table '.$wpdb->prefix.'xmt_twt add unique `acc_nme_twt_id` (`acc_nme`, `twt_id`)';
$wpdb->query($sql);

So, the '.$wpdb->prefix.' will be replaced with your table prefix.
It'll be ridiculous if we didn't aware of table prefix.

I'm not sure why you can't run that query.

If your prefix is ga_, then empty the that table and run this query

alter table ga_xmt_twt add unique `acc_nme_twt_id` (`acc_nme`, `twt_id`)

Yes that's what I did - and we are back to 8 tweets again.

I have worked for Oracle for the last 6 years so that prefix change was pretty obvious 🙂

I have a similar problem.  I have it set to show only two tweets, but to not show "include replies from you". However if one of the last two tweets is a reply (a conversation) then only one tweet will show.  This sort of makes sense, but after this, it never grabs two tweets again even though there are two in a row which are not being filtered out.

Deleting stored tweets, and then grabbing new tweets solves the problem for about a minute (the time set for cache expiry).

Any ideas how to fix this?

Can you check your database (see the wp_xmt_twt table)?
Did you see something unusual there? (Ex: too many records, duplicated tweets)

Hello. I've been using the My Twitter plugin for over a year and a half and have just recently been having a problem with it. Since one of the previous updates, it only shows one or two tweets maximum, even though I have it configured to display five. I've tried a bunch of things, including uninstalling it/deleting files, but the problem persists. I believe this started two updates ago, but it might be one. I'm sorry I forget the exact time it started.

Can you offer any advice? Other than getting a new plugin, of course.

Thank you.
