Well this is what I did and it worked first go, successfully sent a 9 meg file.
Went to
public_html/wp-content/plugins/contact-form-7/modules/file.php
Saved a backup copy, and made a modified copy. In the modified copy I changed the file size from 1mb to 10mb, then added a zero after the 1 on all the instances of “$allowed_filesize = 1048576” “$allowed_size *= 1024” & “$allowed_size *= 1024 * 1024” saved it and pasted it over the original file.
Example modified code below
$allowed_size = 10048576; // default size 10 MB
foreach ( $options as $option ) {
if ( preg_match( ‘%^filetypes:(.+)$%’, $option, $matches ) ) {
$file_types = explode( ‘|’, $matches[1] );
foreach ( $file_types as $file_type ) {
$file_type = trim( $file_type, ‘.’ );
$file_type = str_replace(
array( ‘.’, ‘+’, ‘*’, ‘?’ ), array( ‘\.’, ‘\+’, ‘\*’, ‘\?’ ), $file_type );
$file_type_pattern .= ‘|’ . $file_type;
}
} elseif ( preg_match( ‘/^limit:([1-9][0-9]*)([kKmM]?[bB])?$/’, $option, $matches ) ) {
$allowed_size = (int) $matches[1];
$kbmb = strtolower( $matches[2] );
if ( ‘kb’ == $kbmb ) {
$allowed_size *= 10024;
} elseif ( ‘mb’ == $kbmb ) {
$allowed_size *= 10024 * 10024;
