Request for Review FAILED!!!

I'm using an "Email-Attachment Review Process". I receive a manuscript, i select and assign a reviewer from the list of registered reviewers and i click on the mail logo in order to send the request. the OJS gives me a default email where i ask the reviewer to collaborate but when i click on SEND but i receive two different errors then:

1) * Error Code 64: Host not available
* Background: The connection to the Web server was lost.

or

2) Error Code 404: Page not found

the error page is: http://pgrn.bioversity.cgiar.org/ojs/in ... fyReviewer

This problem comes out when the attachments pass 300kb. Is there a specific setting that i can edit? i only found the maximum file upload size which is set to 2Mb. i found a "HTTP_KEEP_ALIVE=300" under Apache Environment and a "Keep_alive=300" under HTTP Headers Information... could it be one of these?

please help me! this is urgent :(

thank you in advance!!

Hi Marco,

From docs/FAQ:
2) Uploads of large files fail inexplicably.

A: This can be caused by certain Apache or PHP settings.

Apache 2.x has a LimitRequestBody directive that, if set to a low number, can lead to this behaviour. In particular, the default PHP packages for recent versions of Red Hat Linux set LimitRequestBody to 524288 bytes in /etc/httpd/conf.d/php.conf.

Low values for the PHP ini settings like post_max_size (default "8M"), upload_max_filesize (default "8M"), and memory_limit (default "8M") can also cause this problem.

Hi Alec, thanks for your reply.

- post_max_size is set to 8M
- upload_max_filesize is set to 2M
- memory_limit is set to 8M

if i start a submission and upload a 1.8M file everything works fine so why an email attachment of 305K doesn't work? Shouldn't the limit work the same for both uploads and attachments?

Hi marco,

Some firewall products cause this kind of problem by watching for particular kinds of content in request strings; one product, for example, blocked all requests containing the words "DELETE" and "FROM" in that order in a misguided attempt to block SQL injection attacks. Of course, that content may well appear in a valid request, particularly as the request gets longer. I'd suggest that you try toying with your firewall, if you're able, to see if it's being accidentally triggered by the request.
