    Hello Sergey,I would need your help once again. This time I would like you to install Sphinx Search on my server and configure it.I want to use and integrate it with my forum but you don’t need to develop anything because there is already a plugin for it:https://marketplace.digitalpoint.com/sphinx-search-for-vbulletin-4.870/itemSo I need you to install Sphinx Search for me as well as the plugin I just mentioned to make Sphinx work with vBulletin. Both comes with installation instructions, if you need them. I think you told me once, that you already worked with Sphinx, so I believe you are perfect for this job.I really hope you have time for it and please get in touch soon.Thanks a lot.

    Hello,some people have complained that they cant sent me emails or rather their emails get refused and that is the message they get:--------------------------------------------------------------------------------------------------This message was created automatically by mail delivery software.A message that you sent could not be delivered to one or more of its recipients. The following addresses failed: SMTP error from remote server after RCPT command:host mail.xxxx.de[84.200.xx.xxx]:554 5.7.1 Service unavailable; Client host [212.227.xx.x] blocked using dnsbl.sorbs.net; Currently Sending Spam See:http://www.sorbs.net/lookup.shtml?212.227.17.8 --------------------------------------------------------------------------------------------------So I guess some email blocking software is installed on my server but it blocks a lot of (important) emails that are not spam, so I think I want to disable that service.In addition to that task maybe a quick look if there is anything else that is malfunctioning in terms of sending and receiving emails.Hope to hear from you soon.

    Hi,We had a new site built www.wonderlandwigs.com in prestashop in September and as soon as it was lunched we have had massive problems.After further investigation we noticed every now and then it was using 100% of the cpu and 100% of the Ram.We then agreed after looking in the forums we needed to have the site upgraded to 1.4.9.0Because the older version was known to have bugs that could make this problem happen.This did not fix it so we changed over to a dedicated server with lots more power. Double the ram so now the ram is using may 75%This did not fix the cpu issue. Top Processes User Domain % CPU Process wonderla wonderlandwigs.com 94.3 /usr/bin/php /home/wonderla/public_html/category.php wonderla wonderlandwigs.com 93.8 /usr/bin/php /home/wonderla/public_html/category.php wonderla wonderlandwigs.com 92.5 /usr/bin/php /home/wonderla/public_html/category.phpPrestashop version 1.4.9 with custom template (attached) with SSL Server snapshop(WHM):http://awesomescreenshot.com/03fm49a28 PHP info;http://www.wonderlandwigs.com/phpinfo.php Server info:MySQL version : 5.1.65-cllArchitecture: x86_64Perl version: 5.10.1Apache version: 2.2.23Please can you take a look???Best regards Robert McClements
