Upgraded to PHP 7.1 - Twitter microblogging has stopped working

My site http://www.2499atc.org was working fine, collecting tweets with #team2499 in the text and publishing them to Easyblog.

I have upgrade the site to PHP 7.1 and everything is working except the microblogging.

THe cron script runs and retrieves the tweet AND publishes it to Easyblog but 5 minutes later it does the same again and again, continually publishing the last tweet everytime the cron job runs.

When I manually call the script using http://www.2499atc.org/index.php?option=com_easyblog&task=cron&debug=1

it gives an Error 500 in some browsers and in others I see the words

0 - Call to a member function find() on boolean

So the script seems to be crashing out before completing.
Hey Martin,

Can you update your Joomla backend and FTP access at http://stackideas.com/dashboard/site so we can better have a check?

it seems like I hitting this when i login from your backend, can you activate that user account from your backend?


Warning

Login denied! Your account has either been blocked or you have not activated it yet.


By the way, it would be best if you can setup FTP user account for us is because there got risk if modify the file through your Joomla backend file manager page, if modify wrong file or wrong php syntax, it will cause me unable to access backend the file from your backend to revert back the changes.

Login now enabled

I do not run FTp for security reasons. Instead I run Webmin on port 10000

You can check my attached screenshot below, this is what i hitting : 


This page isn’t working



http://www.2499atc.org didn’t send any data.

ERR_EMPTY_RESPONSE


I suspect your server already blocked other country IP address access your site.

is it possible add my current IP address into your server whitelist and see if we can access?

175.139.128.56

I can confirm the file simplehtml.php is present

Hm, that was strange, because based on what i see, it seems like that error is referring this function unable to get call.

I cannot see a specific block on the country or IP level (although my server does have that capability)

I have now whitelisted malayasia and 175.139.128.56

Hm, I still unable to access it

Currently I am not really sure why your site hitting this error unless I can access your webadmin then troubleshoot this issue on your site.

For now, can you try temporary comment out these 2 code and see how it goes? You can check my attached screenshot below.

Hi

I think I have found the blocker that was stopping webmin access, should work now.

I have also commented out those lines and it now works ok. I have left them commented out and turned back on the cron job to see if it is ok when run automatically rather than debugging from the browser.

Perhaps you can let me troubleshoot first before you turn on back the cronjob, because i can access your webmin now.

I get the same error again.

Remember it seems to need a tweet to collect to provoke the problem. I have put in a tweet and it has occurred. Once it hs run successfully through the code (with the affected bit commented out) then it seems to set a marker that means it does not try to retrieve the same tweet again?

Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

It might be because of this reason, is it can put a new tweet from your Twitter account, then update me again? I would like to troubleshoot this issue again.

Thanks for understand.

So strange, one of the php constant return this value "Maximum file size to be scanned" so causing this issue, by right it should return '6000000' which we defined on the PHP file.

For now I've temporary change this MAX_FILE_SIZE value to 6000000 from this file JoomlaFolder/administrator/components/com_easyblog/includes/simplehtml/simplehtml.php , it should work fine now.

But I feel very curious why it return this "Maximum file size to be scanned" instead of the 600000 value.
Can you add 1 more time tweet from your Twitter, I would like to test whether some of the 3rd party plugin cause this issue or not.

Thanks Martin, I think it will not related either you using PHP 7.1 or PHP 5.x, I found out this 3rd party plugin causing this issue System - Centrora Security Activation Plugin, if i disabled it, it will work correctly then fetch the tweet to Easyblog.

It would be best if you can consult with this 3rd party developer regarding this.

You can share this following point to them and see how it goes.

Based on what my troubleshoot, i noticed when we define this 'MAX_FILE_SIZE' to 6000000 value :


define('MAX_FILE_SIZE', 6000000);

But it return to us this sentences "Maximum file size to be scanned".

Centrora have identified that a recent patch is re-defining one of the system variables. They have corrected this as everything is now working fine

Thanks
