Blank screen when trying to load plugin

Take a look inside your PHP error logs, this is usually caused by a fatal error of some kind.

If you go to another page (like Optimization) does it work? What does the Optimization page report for memory usage?

Thank you for your quick response. The menu on the left does not load correctly for me, so I loaded the plugin on a different WordPress site and was able to grab a few URLs and from there I could start visiting other pages.

My logs rotate weekly and in the past week I see nothing when I search for the /wp-statistics/ dir. For today, the closest thing I can see is this error:

[Sun Apr 05 06:31:42 2015] [error] [client XXX.XXX.XXX.XXX] (70007)The timeout specified has expired: ap_content_length_filter: apr_bucket_read() failed

Is that error associated with WP Statistics? Otherwise, there are no related errors.

Yes, I Can see some other pages, but not all. Here are the results of trying to view those pages:

1) Optimization page appears fine. And here are some data from that page:
Memory usage in PHP: 80,465,032 Byte
WP Statistics Version: 9.1.2
PHP Version: 5.3.3
PHP Safe Mode: No
jQuery Version: 1.11.1
cURL Version: 7.19.7

2) Browsers page only loads loads the Browsers and Platforms tables with a very long list on each. And below that, a few tables are loaded with some data but most tables are blank.

3) Exclusions loads fine. And I see “Attention: Exclusion are not currently set to be recorded, the results below may not reflect current statistics!”

4) Hits appears fine. I tested checking different time periods and they all appear to load fine.

5) Online Users appears fine.

6) Pages dow not load. The top and left navigation for WordPress load, but not the plugin’s content. When I View HTML Source I again see this at the bottom of the page:

<script type="text/javascript">
	jQuery(document).ready(function(){
		postboxes.add_postbox_toggles(pagenow);
	});
</script>

7) Referrers load only the text “All (1387713)” at the top. So I assume because there are so many it is timing out?

8) Search Engine Referrals appears fine.

9) Search Words appears fine.

10) Top Visitors Today appears fine.

11) Recent Visitors loads fine and at top I see “All (1396780)” and “Page 1 From 55872” at the bottom. So there must be loads of data in there.

Thanks for your advice.

What is your script timeout limit set to on your web server?

90 seconds. I can increase it, but that will be server-wide and I’d rather not do that. Is there another method you suggest? The 90 seconds is already a lot.

Agreed, 90 specs should be lots.

How many rows are in the database tables?

You mean Records or Rows? Or same thing?

For Records, in the entire WordPress installation it has 2,292,267 total with 1,401,531 coming from wp_statistics_visitor and 384,197 from wp_statistics_pages

It’s probably time to purge some data, processing that many rows could take more time/resources than you’ve allocated.

Is there a way to retain the high-level totals from the past when data is purged? For example, ridding the tables of specific log data but retaining the “totals”?

What’s the best way you suggest to purge data?

Many thanks~

Go to Statistics->Optimization->Purging, this will remove old data and keep the “historical” totals for you.

Of course backup your database before you do this, just in case.

You can also setup auto purging through Statistics->Settings->Maintenance.

Thank you. I set Purging and will wait for wp cron to run. The Statistics->Optimization->Purging will not load for me yet, but I assume it will load fine once wp cron runs.

Yes works well now. Many thanks~

No problem.
