Export does not work

try going to Memphis Doc>Options>Test Server Compatibility>

Look at Recommended Maxim PHP Input Vars what does it say?

Was 1000 (recommended values)
Increased it to 5000.
No success

try editing your php.ini files max_execution_time

make the value bigger.

eg. max_execution_time = 10 is ten seconds.

max_execution_time = 390

Not better …

The zip file is correctly created but not send. (approx. 277MB)
Since all php.ini settings seem to be fine, I guess it is a webserver setting, which I cannot modify.
I am running it on a shared hosting site and my provider does not allow to modify theses settings …

these could also be the issue.

upload_max_filesize = 1000M
post_max_size = 1000M

no, both are set to 999M

I checked http traffic … for about 14 seconds (about the time needed to create the zip file) the request remains open … and comes then with a result 500 and an empty body.

Seems that it does not send the zip file for some reasons …

try looking at you system tmp folder, check if the zip file is there.

Zip file is there, I can watch it being created …
But the response from the server is a 500 .
Apparently the function below is executed and the if (file_exists($file)) in function mdocs_download_export_file($file) gives true … I receive a header with Content-Type: application/zip and so on, but Content length is wrong and body is empty … and status is 500.

So as I said … maybe the webserver has some restrictions to send a file of that size (277MB) this way …

That’s the response after clicking the button to export the library

Content-Length: 0 is the problem. Somehow filesize($file) does not give the correct value

What type of sever are you running, Windows Os seems to have a problem

CloudLinux, shared hosting at my hosting provider

Okay, I’ll take a look next week and see why the file is returning a zero value.

try this:

open the file mdocs-downloads.php and add this line below line 44:

$fp = fopen($file, "rb");
fseek($fp, 0, SEEK_END);
$size = ftell($fp);
fclose($fp);

then change line 55 to this:

header('Content-Length: ' . $size);

let me know the results.
