I had the same problem, and I solved it.

if you are using wamp for your localhost then click on the wamp green icon that is running and press on PHP directory, then you will see php.ini file

if you dont use wamp software, then just find the php.ini file and open it. and search for upload_max_filesize. you should find rows like the bellow one:

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 2M

by default the upload_max_filesize is 2 megabyte. Just simply change it to
upload_max_filesize = 200M (200 megabyte)

then save your php.ini file and restart your services and it will work without any diverticulitis :) 

Things have been changing for quite some time in the SEO world. Hence, new trends have finally surfaced. Things that didn’t matter a few years ago are now of vital importance and companies are constantly making use of them to get more traffic. Here are a few such emerging trends in the SEO world:

• Mobile Search

According to a study conducted by Google, the queries from smartphones and tablets worldwide increased 80% year over year in 2012. Keeping that in mind, it has now become extremely necessary for website owners to update their strategies to cope up with the high number of mobile searches being conducted every day. The only way to keep up with this trend is to prepare the websites for mobile searches and to include the use of mobile specific web formatting.

• Twitter

Twitter is a social networking website like many others but its biggest advantage is its use for link building. Businesses can easily tweet their message and website on twitter. It is an easy way to attract genuine potential customers as the people who click on your link will already be interested in you (because of your description in the tweet). Apart from that, you can make your tweets re-tweetable and ask people to re-tweet (RT) them. As soon as your followers retweet them, their followers will see it and they might click on your link and re-tweet your tweet as well. Another way that you can get people talking about your company on twitter is to add a “tweet this” icon on your website thus enabling visitors to share your page.

• Quality

With its recent algorithm changes, Google has taken some major steps to ensure that the results provided to the users are of good quality. Hence, all the websites that contain repeated, irrelevant material are now suffering. Your material needs to be original and informative. Due to these changes, businesses now have to make sure that they update their websites regularly in order to convince Google that their material consists of a backlog of accurate content and provides value to the users.

• Google +

Google+ might not be such a trending social networking site, but it is one of the most important “emerging trends” in SEO. Since it’s a Google product, Google can very easily collect information about the interests and personal preferences of users depending on the websites that they visit while they are signed into their Google+ account. This gives a whole new meaning to personalized search. Users can also claim their work by linking it to their Google+ profile. Apart from that, Google can easily access data from Google+ therefore; the results from Google+ dominate the results from all other social networking websites.

• Conversion Rate Optimization

Since everyone wants conversions and not just traffic, CRO has become a very trending topic in the SEO world lately. By optimizing a website such that it provides an overall enhanced yet effortless experience to the users, can greatly increase conversion rates. Due to the increased conversion rates of a website, search engines will be able to rank them better than the websites that only get search traffic.

The Final Say

Trends have been constantly changing in the SEO world and therefore it is becoming extremely important for website owners to familiarize themselves with the latest trends. Whether it is the new algorithm changes in Google or the different techniques used to get more traffic, businesses will have to cope up with the changes or risk getting left behind in this race.

初次使用OpenVPN，然后就碰到一個奇怪的問題，OpenVPN明明已提示連接成功，虛擬的網卡也分配了IP，443和21端口也沒問題，“route print”似乎也有相應的路由項了，但就是上不了youtube、twitter這些網站。然后查日志，發現內容居然是空白的，這才想到是不沒有日志的寫入權限，最后以管理員身份運行，成功了。。。

真相大白，OpenVPN每次連接都會添加條默認路由，自然需要管理員權限。故解決方法如下：

方法1：以管理員身份運行 OpenVPN GUI

方法2：連接openvpn后，添加默認路由“route add 0.0.0.0 mask 0.0.0.0 192.168.21.93”，其中192.168.21.93是網關。
