Some php error occurred after restoring site

[wbread]

Changed to a new server, all fully downloaded to the new server, and there are errors, that's one of them.

PHP Ошибка [Warning]
URI: index.php?option=com_eforum&Itemid=39&task=reply&id=94
Path: /administrator/components/com_eforum/includes/eforum.class.php
Line: 887
Creating default object from empty value
php settings:
error_reporting   E_ERROR
.htaccess
php_flag display_errors off

what could be wrong?

[datahell]

I don't see anything wrong in this line except if you have different line numbers in that file. Do you see this error every time you reply to a post or happened only once?

[wbread]

every time

another one

PHP Ошибка [Warning]
URI: index.php?option=com_content&task=blogcategory§ionid=1&id=1&Itemid=12

Line: 3593
Parameter 2 to botAjaxVote() expected to be a reference, value given

[wbread]

most importantly, it's for all migrated sites.

[datahell]

It is due to the newer php version in your new server.
Such errors are easy to be solved, 99.99% are cause to the existence of ampersand in some functions.

To solve this specific one open file:
mambots/bot_ajaxvote.php
and change line 20 from this:
function botAjaxVote( &$row, &$params, $page=0 ) {
to this:
function botAjaxVote( &$row, $params, $page=0 ) {

Do the same for any other mambot causes you the same error.

It is due to the newer php version in your new server.

thanks

transfer the latest version I think should be no problem?

[datahell]

If, by "last version", you mean Elxis 4.x then it has no such problems.
You may try Elxis Converter to upgrade from Elxis 200x.x to Elxis 4.1

You upgraded to a very new php version without thinking that you have software that is, at least, 4 years old. You will have many similar issues. Check your error log for errors and warnings and fix them one by one.

[wbread]

I just changed the server on which version was newer.
5.3->5.4
I think now how to get the old version

[wbread]

new problem on php5.3.3

URI: index.php?option=com_content&task=view&id=88&Itemid=33
Path: /includes/Core/elxis.php
Line: 3591
Parameter 3 to boteHide() expected to be a reference, value given

bot gives this error only on one site, on other sites there is no problem
it is not used, just activated

[datahell]

I told you what to do with bots. The problem is the ampersant character  &, remove it!

[wbread]

forgot to update all bots on websites

Here are the Backward incompatible changes when migrating from PHP 5.3 to 5.4. One of them is: Call-time pass by reference has been removed.
