White page

Thanks a lot qstudio.

I install other wordpress in another server.

I upload many users using the ‘Import from CSV’ pluging

I have 9,000 users, but when I try to upload crash and only upload a few.

First I upload 519 and your pluging export it Ok

Then I upload more until have 1203 and your pluging export it Ok

Finally I upload more until have 2084 and…. I have the (in)famous white page.

I hope this help you to locate the problem.

Thanks

Thanks – did you also try to activate Error Logging in your wp-config.php – an actual error message from the server would really help solve this problem?

Q

Ok… This is the error:

[25-Jan-2014 19:35:12 UTC] PHP Fatal error: Allowed memory size of 109051904 bytes exhausted (tried to allocate 35 bytes) in /mnt/webc/d0/87/53839987/htdocs/wordpress/es/wp-includes/meta.php on line 578

Excellent and really, as expected.

As you can see, as you increase the number of users you try to export, you also increase the amount of resources used – eventually you hit the limit and PHP stops executing..

However, your PHP limit is very low – 104mb.

I suggest you ask your host to increase your PHP limit to 256mb – you can also validate your PHP settings by running phpinfo()

Q

The error also shows us where the overload happens:

meta.php: 578
$cache[$mpid][$mkey][] = $mval;

which is part of the update_meta_cache() function – so, the calls to get_user_meta() are being cached to save resources on future loads, but in this case, they are also overloading PHP.

One option would be to try using direct $wpdb calls – but this is generally not recommended and it’s not future safe..

All you say sounds for me like chinese ??

If I have to do something more say me and I try to do it (I now go out, but in four hours more or less I return).

Thanks, and I hope you can solve it.

ok – I pushed a new update, with a simple limit range option.. it’s basic, but please try it and see if it helps.

Q

0.8.1 broke all buddypress exports ?? … but the latest release has both a range limit option and perhaps a solution to memory over-usage..

Please try to export your whole list first – if that fails, try to limit the number and see how that helps.

Q

Excusme for my delay, but the night go longer than I expect ??

I try your new version and look perfect….thanks, thanks, and thanks….

In my test site, with 2,084 users I can export all.

In my oficial site, whit 8,585 still I have the white page, but with the new feature of limit range I can broke it in part…

The only thing I don’t know wich is the ‘offset start number’.

Thanks.

offset is the number to start the export from

for example:

1st export — 0( offset ) — 1000 ( total number )

2nd export — 1000 ( offset ) – 1000 ( total number )

3rd export — 2000 ( offset ) – 1000 ( total number )

Q

If you’re happy – please rate the plugin and mark this request as closed.

Q

Thanks… I rate it, Is the less I can do for your effort.

Anyway, I try your export directions, but whit

1st export — 0( offset ) — 1000 ( total number )

do it perfect, but with

2nd export — 1000 ( offset ) – 1000 ( total number )

say me ‘No users found.’ and as I say you I have more than 8,000 users

Otherwise, I select a lot of costum fields to export, but they don’t be stored, and I have to select the next time I have to export all the metas again… It’s possible to implement an option to stored it…. it’s only a idea, for me is not urgent and I understand you don’t have time to do all the time my ideas…

The only thing I yes want your help is for the exportation limits now.

Thanks again

Hi Qstudio,

Only for your information.

I finally can export all the dates, but don’t works exactly as you say…

I have to put:

1st export — 0( offset ) — 1000 ( total number )

2nd export — 1000 ( offset ) – 2000 ( total number )

3rd export — 2000 ( offset ) – 3000 ( total number )

etc….

If I put:

2nd export — 1000 ( offset ) – 1001 ( total number )

It only export 1 user.

Thanks

Hi – yeh, I wrote the answer 3 times – each time differently, quickly before I went out.

The final answer – 0 – 1000, 1000 – 2000, 2000 – 3000 is correct, as you’ve seen!

Good news, I’ll close this topic.
